CRUSTACEA. 



one behind; cardiac region with obsolescent tubercles. Feet pubes- 

 cent, moderately long; hand slender, broader at base; fingers nearly 

 or quite contiguous, slender; fifth joint of posterior feet twice as 

 long as wide. First joint of outer antennae spiniform at outer apex, 

 and on outer side 2-5 spinulous.

 head, enlarged six diameters; c, side view; d, female hand; d', male; 

 e, extremity of last pair of legs; /, male abdomen, five diameters; g, 

 female abdomen, ibid. 



Shores of New South Wales, Australia. 



Length of carapax, seven lines; greatest breadth, four and a half 

 lines; breadth of beak at tips, one and three-fourths lines. 



The buccal area is a little broader than long; the third joint of the 

 outer maxillipeds is as long as broad, with the anterior margin entire 

 and rounded ; the fourth joint articulating in a large emargination of 

 the inner anterior angle of the third. The pterygostomian area has 

 a single spine on the margin. The beak extends forward in the line 

 of the surface posterior to it, and owing to the tumid character of this 

 part of the carapax, the direction of the beak is inclined downward 

 and forward. It almost covers the outer antennae throughout. Of 

 the lateral spinules of the carapax the first is the post>orbital ; then 

 there are two, one nearly over the other; then, posterior to these on 

 the sides of the branchial region, two or three others. The surface 

 of the carapax bears a few tufts of setae on ite small tubercles. 



GENUS PUGETT1A (Dana). 



Carapax depressus, superfide fere inermis, spind proeorbitali promi- 

 nenti instructiis, margine pone orbitam utrinque expanso. Articulus 

 pedurn 4 posticorum 5tus cylindricus. 



Carapax depressed, r early unarmed above ; a stout prseorbital spine 

 on either side behind the orbit, sides much expanded; fifth joint of 

 the four posterior feet cylindrical. 



This genus differs from Leucippa, which it resembles in appearance,
