268 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 21 



An occasional hairy specimen, including a 27 mm male and a 14.5 mm 

 female, was found. Smaller individuals of Chorilia longipes (23 mm and 

 under) had numerous vesicles on rostrum, antennae, eyestalks, legs, and 

 on the low portions of the posterior part of the carapace, a feature 

 reminiscent of Rochinia vesicularis. 



It should be noted that the figure used by Rathbun (1893a) and by 

 Schmitt (1921) to illustrate Chorilia longipes is that of C. longipes 

 turgida, and that the description of Holmes (1900) is a composite of the 

 northern and southern forms.

 covered with a sparse down. Rostrum well developed, formed of two 

 rostral horns, united at their base, divergent near their extremity. Supe- 

 rior orbital margin smooth and without a spine. Basal antennal article 

 long, slender, and forming only an incomplete flooring to the orbit; 

 jutting out beyond the orbital margin and appearing at the sides of the 

 rostrum. Movable flagellum greatly developed. Eye retractile into a 

 hollow fossette at the base of a tubercle limiting the hepatic region in 

 front. Merus of the external maxillipeds notched at its anterointernal 

 angle to receive the palp. 



Chelipeds rather long, but feeble [in females and young males] ; 

 fingers terminating in a sharp extremity, finely denticulate and in contact 

 at their terminal portion ; pollex bearing near its base a large tooth, cor- 

 responding to an excavation of the cutting edge of the dactyl. Arm bear- 

 ing a more or less pronounced crest above. 



First pair of ambulatory legs much longer than the others; the fifth 

 very small ; the merus much compressed and bearing a projecting ridge 

 above. Last article devoid of denticulations below.
