214 Notes on North American Crustacea. 



PilHiiiniis g'eniBiiatii)^, nov. sp. 



Surface of body and feet above covered with a cream-colored, velvet- 

 like pubescence. Carapax distinctly areolated, and ornamented with 

 scattered granules or small tubercles, from three to six on each areolet. 

 Spines or teeth of antero-lateral margin very short. Two or three 

 tubercles on the superior margin of the orbit, not acute. Lobes of the 

 front prominent, rounded, granulated ; a transverse series of long hairs 

 above the margin. Lower margin of orbit not spinous. In the cheli- 

 peds, both hands are tuberculated above, and granulated on the outer 

 surface. Ambulatory feet long-hairy, pubescent, and studded above 

 with scattered granules smaller and sharper than those of the carapax 

 and hands. The granules and spines are all of a bright ruby color, and 

 present an elegant appearance from contrast with the whitish or cream- 

 colored velvet in which they are embedded like gems. Length of cara- 

 pax, 0.36 ; breadth, 0.49.

PiluiiiBiiis reticulatHs, nov. sp. 



In this species the carapax is less convex than is usual in the 

 genus ; both it and the feet are clothed above with short clavate seta), 

 closely arranged in reticulating lines enclosing small, naked, polygonal 

 areola3, which, on the anterior half of the carapax and on the chelipeds, 

 are mostly each occupied by a tubercle projecting forward, but flattened 

 on its superior and posterior surface. There are about twelve tubercles 

 on the carapax, excluding marginal ones, and about thirteen on each 

 cheliped. On the ambulatory feet the naked areolse form deep cavities 

 not occupied by tubercles ; about two areolae occupy the width of the 

 foot. A few much longer and larger clavate setae are dispersed among 

 the short ones which clothe the general surface. Antero-lateral margin 

 distinctly four-toothed, not including the external angle of the orbit ; 

 the anterior tooth is situated rather on the sub-hepatic region. A tooth 

 on the sub-branchial region beneath the penult tooth of the antero-
