A REVIEW OF THE MYSIDACEA 111 



mission locality 321, off Cape Cod, 29i/ 2 fathoms, 1879, 1 male; U. S. 

 Fish Commission locality 322, off Cape Cod, 67 fathoms, 1879, 1 

 female ; Fish Hawk stations 993, latitude 40°28' N., longitude 70°44' 

 W., 39 fathoms, September 7, 1881, 7 adults, 8 immature males; 1089, 

 Cape Cod Lighthouse, 110 fathoms, August 3, 1882, 1 female; 1090*, 

 off Cape Cod; Speedwell stations 5*, 25*, 30*, 81*, identified by Smith 

 (1879) ; Albatross station 2453*. 



Distribution. — This species is not uncommon off the east coast of 

 North America. Smith (1879) recorded it from Massachusetts Bay, 

 20 to 48 fathoms. I have recorded it from several places in the Gulf 

 of St. Lawrence from 40 to 275 meters and Gardiner (1934) from one 

 locality in the Bay of Fundy.

Erythrops microphthalma G. O. Sabs, 1870b, p. 30, pi. 2, figs. 13-19. 



Erythrops microps Zimmee, 1904, p. 447, figs. 99-101 ; 1909, p. 81, figs. 160-163. 



Occurrence. — Northeast coast of the United States: Albatross 

 station 2046, 1 male. 



Distribution. — New to the American fauna. Widely distributed in 

 the boreal North Atlantic from the coasts of Ireland, Norway, and 

 Greenland in deep water. 



ERYTHROPS ABYSSORUM G. O. Sars 

 Erythrops abyssorum G. O. Sars, 1869, p. 326 ; 1870b, p. 36, pi. 5, figs. 1-12. 



Occurrence. — Northeast coast of the United States: Albatross 

 stations 2046, 1 male, 1 female; 2179, 1 female; 2215, 1 female. 



Distribution. — New to the American fauna. Its general distribu- 

 tion is similar to that of E. microps. 



ERYTHROPS YONGEI Tattersall 



Erythrops yongei Tattersall, 1936b, p. 149, fig. 2. 



Occurrence. — Albatross station 5456, 1 female, 5.5 mm. 



Remarks. — The single specimen is not in good condition, but it 

 appears to agree in all essential characters with the type specimen. 

 Unfortunately it does not throw any further light on this somewhat 

 anomalous member of the genus Erythrops. One addition must be 

 made to the characters given in my earlier description. There is a 

 slender fingerlike process on the eye which originates on the inner 

 upper surface of the eyestalk and projects over the cornea. It is as 

 long as the cornea is deep. 



Distribution. — This species was originally described from a single 

 specimen collected off the Barrier Reef, Queensland, in 400 meters. 

 Its occurrence off the Philippine Islands marks a considerable exten-
