ICONAXIUS CRISTA-GALLI. 129 



one is waoting. Smaller chela with a sharp tooth at the 

 base of the fixed finger ; upper border of the palm also 

 faintly denticulate. 



Palm of the 2^^ legs one third longer than the carpus, 

 chela little shorter than the merus, which is almost twice 

 as long as the short carpus. 



Length of egg-bearing female SO^ii™-. 



3. Iconaxius (Iconaxiopsis?) consohrinus^ n. sp. 



Station 280. Lat. 8°17'4 S. ; long. 127°30'7 E. Depth 

 1224 M. 



Closely related to Iconaxiopsis laccadivensis Alcock, but 

 the carapace (rostrum included) shorter, hardly longer than 

 the first four abdominal somites combined and the proxi- 

 mal tooth on the fixed finger of the larger hand near the 

 finger-cleft indistinct. 



Carapace measuring little more than one third of the 

 whole length. Rostrum very narrow, reaching to the middle 

 or to the distal end of the 2^^ joint of the antennular 

 peduncle, about 3-times as long as broad in the middle; 

 extremity subacute, lateral margins hardly converging, pre- 

 senting three or four small, rather indistinct teeth. Median 

 crest extending until near the tip, entire, dividing itself 

 posteriorly into two rather indistinct ridges that are short, 

 reaching not so far backward as the lateral ridges. In 

 Icon, acutifrons Sp. Bate and in Icon, farreae Ortm. the 

 rostrum is more triangular, broader at the base and the 

 lateral margins diverge more strongly backward. 



Carapace and abdomen as in Icon, acutifrons. 



Eye-peduncles barely reaching to the middle of the 

 rostrum, cornea facetted and of a pale yellow-green colour. 



Both pairs of antennae as in Icon, acutifrons. 



Lower angle of the carpus of i^* pair of legs obtuse. 

 Larger chela of the male little shorter than the carapace; 

 the palm, that is slightly longer than high, is once and 

 a half as long as the fingers that leave proxiraally a small
