Diagnosis. Kali indica can be distinguished from all species of Kali except K. falx by the teeth in lateral series of premaxilla seven to 11, caniniform, elongated, slightly curved, type 4, widely spaced (vs. teeth in lateral series of premaxilla 13 to 33; recurved, with ventral attachment, closely spaced in K. parri; needle-like, closely spaced in K. kerberti and K. macrodon and anterior part fourth of K. normani; caniniform but not very elongated in K. colubrina); first tooth of lateral series of premaxilla longest, with tight type 4 attachment (vs. first tooth of lateral series of premaxilla not remarkably enlarged, smaller than adjacent teeth, with loose types 4 attachment or with ventral attachment to bone); teeth in mesial series of premaxilla three, fang-like (vs. teeth in mesial series of premaxilla four or 15; not fang-like in K. macrura, K. parri, and K. colubrina); teeth in lateral series of dentary six to eight, very elongated, curved, type 4, widely spaced (vs. teeth in lateral series of dentary 12 to 32; recurved, with ventral attachment, closely spaced in K. parri, needle-like, closely spaced in K. kerberti and K. macrodon and anterior part fourth of K. normani; recurved in K. colubrina).

Kali indica can be distinguished from K. falx by the larger eye, orbit width 15.4–22.7% and orbit height 12.5–18% in head length (vs. eye small, orbit width 11.2–16.0% and orbit height 9.7–12.4% in head length); basihyal elongated and straight, pointing forward (vs. basihyal reduced and strongly curved, pointing ventrally); first tooth in lateral series of premaxilla enlarged, 15.2–16.4 % in premaxillary length, slightly curved, not projecting anteriorly (vs. first tooth in lateral series of premaxilla remarkably enlarged, 17.2–20.5% in premaxillary length, sickle-shaped, projecting anteriorly); first tooth in mesial series of premaxilla anterior to level of anterior nostril, and to second tooth of lateral series (vs. first tooth in mesial series of premaxilla below level of anterior nostril, and beside second tooth of lateral series); first tooth in mesial series of dentary beside second tooth of lateral series (vs. first tooth in mesial series of dentary between second and third teeth in lateral series).

Description. Moderate-sized species of Kali, largest specimen examined 207.7 mm SL. Meristic data summarized in table 2, and morphometric in table 4. General body pattern as described for genus.

Dentition. Teeth present on premaxilla, dentary, palatine, upper and lower pharyngobranchials; premaxilla and dentary as illustrated in figure 1 A, and summarized in table 1. Tooth crown length 14.9–20.5% in tooth length. Premaxilla elongated, arched in lateral view, with teeth arranged in two series: lateral and mesial. Lateral series in single row; teeth type 4, caniniform, with flange, widely spaced. Anteriormost tooth longest, 15.1–16.4% in premaxillary length, slightly curved, inserted at antero-ventral tip of premaxilla; tightly attached to bone, with restricted movement. Following teeth curved, decreasing in size from anterior to posterior, at lateral edge of premaxilla; second to fourth teeth at anterior half of premaxilla, between level of anterior nostril and posterior margin of eye; posterior teeth needle-like, at posterior third of premaxilla. Mesial series in single row; teeth with ventral attachment, recurved, fang-like, largest tooth 23.4–33.5% in premaxillary length, with flange; widely spaced, decreasing in size from anterior to posterior; base of first tooth below anterior nostril, beside second tooth of lateral series; second tooth below anterior margin of eye, between third and fourth teeth of lateral series; and third tooth slightly posterior to posterior margin of eye, between fourth and fifth teeth of lateral series.

Dentary elongated, moderately arched in lateral view; teeth arranged in two series: lateral and mesial. Lateral series in single row; teeth type 4, caniniform, slightly curved, with flange, widely spaced; anterior tooth longest, remaining teeth decreasing in size from anterior to posterior, opposite to premaxillary teeth. Mesial series in single row; teeth with ventral attachment to bone, recurved, fang-like, largest tooth 20.1–29.3% in dentary length, with flange. Teeth widely spaced, decreasing in size from anterior to posterior; base of first tooth beside second of tooth of lateral series; second tooth halfway between third and fourth of teeth of lateral series, and third tooth slightly anterior to fifth tooth of lateral series. Single specimen (MNRJ 26693) with small fourth tooth in mesial series, at posterior end of dentary.

Palatine teeth type 4, conical, slender, with short flange, in single row. Lower pharyngeal teeth type 4, needle-like, without flange, in single row; upper pharyngeal teeth type 4, conical, slender, without flange, in one to two rows. Teeth absent on gill arches, basihyal and basibranchials.

Color. Skin covering body fragile, missing in most specimens, description based on MCZ 164764. Epidermis black, thin and fragile, completely destroyed or restricted to small patches in all specimens examined; dermis thin, transparent with widely spaced melanophores. Peritoneum transparent, with moderate concentration of melanophores. Orobranchial chamber pale, with few widely-spaced melanophores in sides of mouth, opercle and membranes between branchiostegal rays; gill arches and filaments pale.

Distribution. World-wide in the equatorial, tropical, subtropical, temperate and subpolar regions: in the Atlantic from 40° N to 40° S; in the Indian from the type locality, 16°56’ N, 92°33’ E; in the Pacific 31° N to 43° S; and in the Southern Ocean between 50° S and 60° S (Fig. 3).

Bathymetric distribution. Bathypelagic zone; more frequently recorded in depths between 1400 and 2500 m (mean 1954 m). A single record from above 1000 m (935 m); deepest record at 3300 m.
