Description
TABLE 3. Proportional morphometric and meristic characters of three new species of Allinectes: A. istiophorus, A. busbyi, and A. nanstanorum. Morphometric data are given in percent standard length and presented as the range, followed by the mean +/– standard deviation (SD). Data not available are indicated with an en dash.
