a small spine or spinule on the intestinal region and several of the 

 same on the branchial regions, especially on the margin. The 

 large gastric spines are in a plane nearly parallel with that of the 

 rostrum and are slightly divergent from each other. There is a 

 strong ridge leading from it to the outer margin of the outer spine 

 of the orbit; from this ridge a secondary ridge curves around to 

 the posterior hepatic spine. 



The eyes have slender stalks and a large acute tubercle on the 

 anterior side of the extremity. The basal segment of the antenna 

 is armed with three downward pointing spines of which two are 

 on the outer margin; the spine at the anterior angle is directed 

 obliquely forward; two succeeding segments with a few sharp tu- 

 bercles or granules on the under surface; third segment about four 

 times as long as wide. 



Manus of chelipeds very elongate, about three times as long as 

 its greatest height and increasing in height from the proximal to 

 the distal end; its spines are large at the base but acuminate at the 

 tips. Fixed finger stronglj'^ inclined; the fingers gape moderately, 

 and three or four teeth near the base of the dactylus are united in a 

 submolar; the proximal two-fifths of the upper surface of the 

 dactylus is spinulous. 



First two legs heavily armed; third and fourth pairs have two 

 rows of small, slender spines on the lower side of the merus; ter- 

 minal spine on all the merus joints long; dactyli with several fringes 

 of short hair. 



First, second, and sixth segments of abdomen with one median 

 spine; seventh segment with a spine each side of the middle, while 

 the other segments have two spines each side of the middle; there 

 is also a spine near the outer margin on all the segments save the 

 first. Sixth segment a little wider than long, a forward-projecting 

 lobe at distal corners. 



This species has much in common with C. goodridgei McArdle;* 

 but the latter has no supraorbital spine; the lateral gastric spines 

 are directed strongly outward; the eyes are more robust; the 

 movable segments of the antennal peduncle are armed with spines; 

 the last two legs have no spines on the under side of the merus 

 joints.
