Tliis is one of thu most abundant of all New England Amphipoda, 

 being found in greater or less abundance in a very large proportion of 

 the dredgings from the shallowest water down, at least, to 400 fath- 

 oms, and from all kinds of bottom, though in less abundance in mud 

 than among sand and shells. I have collected it at Great Egg Har- 

 bor, New Jersey, where Say's original specimens were obtained, and 

 at various points along the New England coast from Connecticut to 

 the Bay of Fundy. It was dredged by Mr. Harger and myself 

 while on board the Bache in 1872, on St. George's Banks, and in 430 

 fathoms east of these Banks, north latitude 41° 25', west longitude 

 65°, 42'3'. It was obtained in abundance in and off Halifax Harbor, 

 Nova Scotia, by the U. S. Fish Commission, in 1877 ; and I have ex- 

 amined specimens dredged in the Gulf of St. Lawrence by Mr. 

 Whiteaves, and on the coast of Labrador by Prof. Packard. Kro- 

 yer's specimens of Glauconome Uncopis were from Gi'eenland, and 

 Norman reports it, under the same name, as taken in 100 fathoms in 

 Davis Strait by the Valorous Expedition. Boeck records the same 

 species from Spitzbergen and Norway, and G. O. Sars reports numer- 

 ous specimens, obtained by the Norwegian Expedition in 1876, from 

 412, 417, and 520 fathoms, in the area of cold water off the west 

 coast of Norway. 



In life, the body of the animal above is usually bright red more or 

 less mottled, especially upon the sides, with white; the outer sur- 

 faces of the larger gnathopods are broadly marked with bright red, 

 and the antennulse and antennae arc annulated with the same color. 

 In some individuals, especially from muddy bottoms, the red is 

 nearly all wanting ; in others the red appears, to the naked eye, to
