— PUGETTIA VENETIAE, FEMALE (50268), 

 MAXILLIPED, X 10.5 



the minor hepatic spine is a little below the level of the major one, 



and is straight. Postorbital spine a little behind the eye, slender, 



similar to the two large lateral spines, but not so long-pointed. 



Preorbital spine also large, directed forward; in front of it, is visible 



the antennal spine. Rostrum deeply 



divided by a wide sinus: outer mar- 

 gins of horns subparallel. The basal 



antennal article has, besides the 



antero-external spine, one further 



back on the outer margin, while in 



the same line but behind the orbit 



there is another small spine. A small 



subhepatic spine; also a row on the 



subbranchial and on the pterygosto- 



mian region. 



Chelipeds of adult male about as 



long as carapace. Ischium spined 



on inner margin ; merus on inner, up- 

 per and inner-lower margins, 4 of the 



upper spines being the longest of all; 



the carpus has 2 spines on inner mar- ^"^• 



gin, a row of four on outer margin, 



and a few spines above and below; a few spinules on upper surface 



of palm at proximal end. Upper and lower margins of palm slightly 



convex; dactylus nearly as long as upper margin of palm; fingers 



narrow, deflexed, toothed within, a very narrow gape at base where 



the teeth are smaller. 



Ambulatory legs subcylindrical, slender; propodites thickest at 



distal end; dactyls with tv\'o rows of sharp, prehensile spinules, and 



a long, light-horn-colored tip.
