128 ICONAXIUS WEBERI. 



Eye-peduucles short, eyes facetted, not pigmented at all. 

 Scaphocerite large, almost reaching to the distal end of 

 the antennal peduncle, stylocerite a little shorter. 



Chelae of 1»* pair of legs about as in Icon, kermadeci, 

 but the larger chela with a strong, broad tooth at the 

 base of the dactylus; smaller chela with an acute, simple 

 or bicuspid tooth at the base of the immobile finger, as 

 in Icon, kermadeci, Icon, parvus etc. ; the fingers once and 

 a half as long as the palm, dactylus strongly curved. 



Carpus of the 2"'! legs longer and more slender than in the 

 other species, little shorter than the merus and than the 

 chela, always longer and distally broader or thicker than 

 the palm ; fingers, in the adult, one fifth the length of 

 the whole chela. 



Eggs few in number, large. 



Length of the male 16^™-, of the female 20mm.. 



2. Iconaxius crista-galli Faxon, var. indica, n. 



Station 267. Lat. 5°54' S. ; long. 132°567 E. Depth 

 984 M. 



Closely related to Iconaxius asper Rathb. from the Ha- 

 waiian Islands, but the palm of the larger chela is less 

 high in proportion to its length and its upper border is 

 faintly denticulate. 



Median crest of the rostrum which appears a little nar- 

 rower than in the type and the acute tip of which is 

 curved upward, armed with 16 small, sharp teeth instead 

 of 7 ; lateral ridges posteriorly more prominent than at 

 the level of the median crest. Lateral margins of the 

 rostrum each with 6 or 7 prominent teeth. Third joint of 

 antennular peduncle barely shorter than the 2^^. 



Carinate upper border of the palm of the larger cheli- 

 pede faintly denticulate along its whole length and termi- 

 nating in a small, sharp tooth ; two or three teeth on 

 the distal border of the palm, between the fingers. Of the 

 two teeth of the dactylus that exist in the type, the distal
