PyCNOGONIDA OF NEW ENGLAND AND ADJACENT WATEKS. 479 



Legs very stout, the three basal joints short and overlapijiiig- each 

 other; fourth joiut as long as the three basal ones, much distended with 

 the ovaries in the specimen described; fifth as long as the fourth, but 

 much more slender; sixth still longer and more slender; tarsus very 

 short, nearly triangular; propodus tapering from the base, slightly 

 curved, armed on the inferior margin with five or six stout curved 

 spines; dactylus curved, acute, about two-thirds as long as the pro- 

 podus. 



All of the legs bear a number of prominent, conical, spiny tubercles. 

 These are arranged in longitudinal rows on some of the joints, i^articu- 

 larly on the fifth and sixth, which thus appear deeply serrate on the 

 margin. The entire surface of the body is rough and more or less hairy. 



Color, in alcohol, light brown. Length 3 millimeters; legs 7.5 milli- 

 meters; accessory legs 3.7 millimeters. 



I have seen only two sx)ecimens, namely:
