Gen. Temorites, n. 



Generic Characters. Form of body short and robust. Cephalic seg- 

 ment well defined, last pedigerous segment confluent with the penultimate 

 one. Front without any rostrum or tentacular appendages. Tail symmetrical, 

 and composed in female of 4, in male of 5 segments. Caudal rami very 

 small, with a limited number of setae. Anterior antennae 24-articulate ; 

 right antenna in male prehensile. Posterior antenna with the outer ramus 

 7-articulate, and about the length of the inner. Mandibles well developed, 

 cutting teeth rather dissimilar, the outer ones unguiform, palp comparatively 

 large, with the inner ramus the more prominent. Maxillae with the palp im- 

 perfectly developed, inner ramus obsolete, outer not defined from the basal 

 part, lamelliform, with strong curved setae. Anterior maxillipeds exceedingly 

 large and powerful, with the distal spines very much elongated and claw- 

 shaped. Posterior maxillipeds normal. 1st pair of legs rather small, with 

 the inner ramus biarticulate ; the 3 succeeding pairs well developed, with both 

 rami 3-articulate, the outer one very strong. Last pair of legs in both sexes 

 simple, not biramous, in female 3-articulate, with the terminal joint long and 

 narrow, spiniferous at the tip; right leg in male much larger than left, with 

 the 3rd joint lamellarly expanded, and carrying at the tip a strong, incurved 

 claw; left leg tapered distally, and carrying a straight apical spine. 



Remarks. This new genus is only provisionally placed in the family 

 Temoridce. It differs, in fact, very materially in some respects from the other 

 known genera comprised in this family, and in certain points exhibits an 

 apparent approach to the Pontellidce. The genus comprises as yet but a 

 single species, to be described below.

 (PL XXX, XXXI). 



Specific Characters. Body in both sexes very short and stout, with the 

 anterior division considerably tumefied, and oval in form. Tail scarcely 

 exceeding l /a of the length of the anterior division, and having the segments 

 very sharply marked off from each other, anal segment smaller than the 

 others. Caudal rami of very small size, each with only 3 plumose setae, and 

 an unciliated bristle at the inner corner. Anterior antennae about the length
