34:6 A. E. Verrill — Decapod Crustacea of Bermuda. 



Our No. 470, which was labelled as jE! Herbstii by Miss Rathbun, 

 has the ratios 1:1.33. Therefore it has nearly the same proportions 

 as E. americanus, in which they are usually about 1 :1.3. The differ- 

 ence in form is, therefore, not very relial)le. The largest example 

 mentioned b}"- Benedict and Rathbun had the carapace 40™'" long 

 and 62'"'" wide, ratio 1:1,55. It was about the same size as the type 

 of our var. minax.

* This belongs to the var. obesKS. It is the figured specimen, pi. xv, fig. 1. 



This is much more active than most species of Eupanopeus. In 

 some cases it may be seen actively running about on the stony 

 beaches, as at Spanish Point, in March, 1901, where it was found in 

 considerable numbers and "very lively" by A. H. Verrill. It was 

 not found at any other place in such numbers. These were of 

 medium size and rather bright colors (Nos. 4042, 4043). They 

 were purplish, varied with yellow and yellowish white; on the under 

 side, pale yellow mottled with bright lavender. (A. H. V.) 



In the Bermudas it occurs mostly under stones and dead corals on 

 rock}^ shores and on the reefs. It was obtained by Jones, Goode, 

 Kincaid, and by the Yale parties of 1898 and 1901, but usually in 

 small numbers or singly. This species, as a whole, ranges from 

 Southern New England to Florida, Texas, Colon, and through the 

 West Indies to Brazil (coll. Yale Mus.). It is abundant from Cape 

 Hatteras southward. The typical variety seems to occur, as well as 

 the var, obesus, throughout its entire range.
