fathoms, rocks and mud, and off the Isles of Shoals !, 35 fathoms, 
clay, mud and sand, 1874. Abundant in 7 to 35 fathoms, rocky, 
gravelly, shelly and muddy bottoms, at various localities in Casco 
Bay !, and taken also near low water mark, among eel-grass !, in 
Portland Harbor, and a single specimen from 48 to 64 fathoms, stones 
and mud, sixteen to eighteen miles east-southeast Portland Light !, 
1873. Found also in abundance in the stomachs of the cod taken on 
West Cod Ledge !, off Portland. Bay of Fundy !, 1864, 1868, 1870, 
1872, 5 to 40 fathoms, but not found in so great abundance as in 
Casco and Massachusetts Bays. Large females carrying eggs were 
also collected at Eastport !, Maine, by C. Hart Merriaiu and E. B. 
Wilson, in April, 1876. Halifax ! Nova Scotia, 1877, common in 16 
to 21 fathoms, stones, sand and red algae; in 18 to 25 fathoms, 
shingly, gravelly, sandy and muddy bottoms; and 16 fathoms, mud, 
at the mouth of Bedford Basin ; and a siugle specimen, in company 
with H. macilenta , in 35 fathoms, very soft mud, in Bedford Basin 
itself. Also off Halifax !, 52 fathoms, sand, mud and rocks, and 57 
fathoms, gravel and stones, 1877. Gulf of St. Lawrence!, 1871, (J.

Mr. Kingsley (List of the North American Crust, belonging to the 
Sub-order Caridea, Bulletin Essex Institute, vol. x, p. 59, 1878) gives 
Massachusetts Bay northward to Europe” for the distribution of 
this species, but, as this is the only record I have been able to dis- 
cover of its occurrence on the eastern side of the Atlantic, I am 
inclined to regard it as an error, although its discovery in Europe may 
very properly be expected. 
A careful examination of a large series of specimens of this species 
shows considerable variation, even in characters which are usually 
regarded of at least specific value. The most important of these 
variations which I have noticed is — 
The presence or absence of epipodi upon the bases of the second 
pair of cephalothoracic legs. The Fabricii differs fi*om all the other 
species of the genus which I have examined in usually wanting 
epipodi at the bases of all the cephalothoracic legs except the first 
pair, while in the other species these appendages are usually present 
upon the bases of the first and second or upon the first, second and 
third pairs ; and on this character it was placed alone in a section of 
the genus by Ivroyer. Among fifty-two individuals (eighteen males 
varying in length from 27 to 39 mni , and thirty-four females varying
