The rostrum is straight or only slightly bent ; on the upper edge 

 are seven to nine regularly spaced teeth, the distal ones smaller ; 

 a single spine is back of the base of rostrum ; carapace not pubes- 

 cent, except on special areas, the hairs are short and soft ; abdomen 

 smooth and glossy ; carapace carinated more than half its length ; 

 abdomen carinate on the fourth to sixth segments ; hepatic and 

 antennal spines present. 



The antennular stalk is longer than the rostrum, about as long 

 as the scaphocerite, not very stout ; the penultimate article is rather 

 elongated. The' preceding joint reaches a little beyond the eye. 

 The eye is large, a little emarginate on the upper side; stalk is 

 short and thick. 



Telson tapers to the acute tip, with a small, sharp distal spine on 

 each side; upper side with two obtuse carinae. Length of body 

 of adult females 60-65 mm, including rostrum. The color of a 

 small specimen, in life, was translucent bluish white, faintly and 

 irregularly marked with brown on the abdomen. According to 

 Hay and Shore it is "translucent white with purplish gray cloud- 

 ings and blotches ; appendages pinkish." 



This was taken at Bermuda by Mr. Goode in 1877, and by the 

 Yale Expedition in 1901. The latter was young, dredged in Great 

 Sound, in 3-5 fathoms. Its range extends from off Chesapeake 

 Bay to Porto Rico. Off Chesapeake Bay, 18 fathoms; off Cape 

 Hatteras, 7 to 27 fathoms; and Fort Macon, N. C. (Smith); 

 Beaufort, N. C., 4 fathoms, and Charleston Harbor, S. C. (Stimp- 

 son) ; Pensacola, Fla., and Porto Rico (Rathbun) ; Bahamas 

 (Rankin). Marcou Pass, Fla. (Kingsley).
