368 A. E. Verrill — Decapod Crustacea of Bermuda. 



MeasurementH nf Bermuda speeimens. 



We found this species very common at Bermuda in the shallow 

 water of inlets and bays, especially at Hungry Bay, in March and 

 April, 1901. Also at Castle Harbor, Long Bird I., etc. It Avas con- 

 tained in the earlier collections of J. M. Jones, G. B. Goode, and 

 others. In the 1905 collection of the Field Nat. Hist. Museum, 

 there are man}^ fine specimens from St. Davids I., Hermit Bay, etc. 

 One of the latter, only 13.5""" long, carried eggs. 



Its range extends from Cape Hatteras to Brazil. Off C. Hatteras, 

 14 fath. Abrolhos Reefs and Caravellas, Brazil (Smith); S. Caro- 

 lina (Ordway); St. Catharine, Brazil (M.-Edw.). Florida (Stimpson).

This is closely allied to C. Dance, of the West Indies and Brazil. 

 The latter has straighter and more equilateral marginal teeth and 

 the male generative appendages are longer and different in form. 



It also closely resembles C. or7iatus in most respects. It can best 

 be distinguished by the longer and narrower intramedial gastric area 

 of the carapace, which is only about twice as broad as long. The 



* This species was based on a small sterile female (figured as a male) from W. 

 Africa. Prof. S. I. Smith first referred it to Callinectes, with some doubt, in 

 1869.
