Milnia bicornuta Stimpson, i860, p. 51. 180. 



MicTophrys bicomutus A. Milne-Edwards, 1872, p. 247: ibid, 1S73-1880 (1873], p. 61, pi. xrv. fig. 2-.*; Rathbun, 1901, p. 72, 



Carapace subpyriform, uneven and covered with rounded tubercles, among which are scattered 

 hooked hairs. Rostrum composed of two stout, rather long horns which may diverge slightly from 

 the base but are often nearly parallel; a strong spine below the front of the orbit; supraorbital spine 

 well-developed and postorbital angle prominent. Branchial area with two or three short spines, the 

 larger one of which usually curves upward. 



Chelipeds moderately strong, the meral and carpal articles somewhat nodose; hand smooth, fingers 

 about two-thirds as long as the palm. 



Length, 14 mm.; width, 10.5 mm. 



Color, in alcohol, light gray; in life, yellowish brown. 



Three immature specimens of this species were obtained in 14 fathoms on the fishing banks off 

 Beaufort in 1915. 



Microphrys platysoma (Stimpson). PI. xxxviii, fig. 9.

Microphrys platysoma A. Milne- Edwards, 1873-1880, p. 62; Rathbun, igoi. p. 72. 



Carapace slightly longer than wide, broadly subpyriform and depressed; surface thickly covered 

 with tubercles and short, stout spines among which are bands and patches of crispate hairs; there are 

 two or three strong spines on each branchial region, a prominent tuberculate boss on the cardiac region 

 and a strong spine on the superior margin of the orbit; anterolateral margin with two laminiform proc- 

 esses, one on the branchial, the other on the hepatic region; rostral horns slender, acute, and directed 

 straight forward. The spine of the basal article of the antenna extends obliqtiely outward and is about 

 one-half the length of the rostrum. 



Chelipeds rather weak, exceeding the rostral horns by less than the length of the hand; meros with 

 a dentate, laminate, superior crest; carpus tuberculate; hand smooth, the palm about twice as long as 

 broad; fingers widely gaping at the base. Ambulatory legs hairy, the meral and caroal articles with a 

 strong spine. 



Length of a male, i8 mm.; width, 16.5 mm.; length of rostrum, 5 mm. 



Three specimens, one male and two females, were taken, at as many stations, on the Blackfish 

 Banks by the Fish Hawk in 1914 at depths ranging from 13 to 16 fathoms.

Carapace as long as or longer than broad, oval; back with tubercles of various sizes and scattered 

 hooked hairs; sides arcuate and armed with five strong teeth (exclusive of postorbital tooth) of which 

 the first is the largest, the second and third are subequal, and the fourth and fifth are much smaller; 

 eye sockets tubular, the distal extremity being bidentate and nearly or quite as advanced as the frontal 

 teeth; the latter are short, conical, and separated by a V-shaped notch. 



Antennae short and fringed with stiff hairs, the first article coalesced with the carapace to form the 

 floor of the orbit, the second article flattened and considerably produced into a lobe on the outer mar- 

 gin. 



Chelipeds of full grown male from one and one-half to nearly two times as long as body, the meros 

 subcylindrical while the carpus and hand are more or less compressed and distinctly angled along the 

 margins.
