Scale mm. plumose setae. The endopodite has 5 segments. The ultimate and penultimate segments are heavily armed with setae, many of which have setules. The chelipeds (Fig. 10 J) are subequal in size; the left being larger than the right. Periopods 2 and 3 (Fig. 10 H-l) have dactyli as long as the propodi. Periopod 4 (Fig. 10 G) is nonchelate. The propodus has 4 corneous granules on the ventrolateral sur- face. Periopod 5 (Fig. 10 F) has 7 granules and 7 long setae on the propodus. Pleopods (Fig. 10 B-C) are biramous. Endo- podite of each bears 2 small hooks. Exopodites of the pleopods on somites 2-4 bear 9 plumose setae, whereas the pleopod of somite 5 has onl> 8 DISCUSSION The purpose of the present study is to extend an earlier work on Pagurus samuelis larval develop- men by Coffin (1960). Coffin did not make a detailed study of the larval appendages, making.
