REMARKS
The specimen collected at station 13078 is exceptionally large (38.8 mm) and probably represents the greatest length this species attains. The plates appear to be old with a considerable amount of erosion. It is interesting to note how reduced the inframedian-latus is in this specimen, when compared with younger ones (Fig. 26). The inframedian-latus seems to lose its function of covering the suture between the lower latera and becomes an eroded small plate situated over the rostrolatus.
Amigdoscalpellum rigidum is a common deepsea pedunculate occurring between 1267 and 4810 m from the Azores, Cape Verde, Iberian, West European and Newfoundland basins (Aurivillius 1898; Gruvel 1905; Young 1998a, b).
