 general color is light-gray, with a few scattered brown specks ; anal seg- 

 ment, light- green; antennae and teotacular cirri, white.

PODARKE C^CA n. Sp. 

 (Pl. I, Figs. 6-8.) 



We found a few specimens of PodarJce differing much from Podarke 

 obscura Verrill ; it may be found to be the young of some species. 



The head (fig. C) was evenly rounded in front and at the sides; 

 nearly straight behind; length to width as two to three; slightly con- 

 vex; no eyes; antennae arising from nearly cylindrical basal articles ; 

 posterior unpaired antenna, arising near the posterior margin, not quite 

 so long or so stout as the others; upper (anterior) pair close to each 

 other, near the anterior margin of the head ; length (without basal ar- 

 ticles) about equal to the length of the head; lower pair arise from 

 the under surface of the head, just outside the upper pair; a trifle more 

 delicate than the latter. 



The iirst segment encroaches laterally on the head, reaching about 

 to the middle line ; it is nearly as long at the sides as the following 

 segment, elsewhere about one-half as long. 



The tentacular cirri are six on each side, not at all crowded, a single 

 pair from each of the first three segments; they have stout and rather 

 long cylindrical basal articles; are very variable in length ; taper uni- 

 formly to a bluntly rounded apex. The feet (fig. V) are quite large, 

 pointed externally, much swollen at base, owing to the origin of the 

 basal i)ortionof the dorsal cirri. 



The dorsal cirri do not extend beyond the feet, are delicate, conical ; 

 base a little swollen. 



Ventral cirri given off at about the outer fourth of the foot; extend 

 about to the end of the foot. 



The segments are deeply incised, much wider than long, slightly con- 

 vex, both from side to side and from before backwards.
