 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 fi*om 48 to 64 fathoms, stones 

 and mud, sixteen to eighteen miles east-southeast Portland Light !,

 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 Merriam and E. B. 

 Wilson, in April, 1876. Halifax ! Nova Scotia, 1877, common in 16 

 to 21 fathoms, stones, sand and red alga3 ; in 18 to 25 fathoms,

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 sj^ecies, 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 eplpodi upon the bases of the second 

 pair of cephalothoracic legs. The Fabricii differs from 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 Kroyer. Among fifty-two individuals (eighteen males 

 varying in length from 27 to 39""'", and thirty-four females varying
