Very abundant at the surface in Vineyard Sound !, January 8, 

 1875, and January 14, 1876 (V. N. Edwards). Massachusetts Bay!, 

 48 fathoms, mud, 1877. Ofl" the coast of Maine!, 102, 105 and 107 

 fathoms, mud and gravel, and mud, 1873, 1874. Bay of Fundy !, at 

 the surface, 1864, 1868, 1872; dredged in 40 to 50 fathoms, rocky, 

 1868; and found in the stomachs of pollock and hake, 1872. Gulf of 

 St. Lawrence !, 50, 70, 210 and 220 fathoms (J. F. Whiteaves). Green- 

 land (Reinhardt, Ltltken). Spitzbergen and Finmark (Goes). Lofo- 

 ten Islands!, Norway (G. O. Sars). 



The specimens taken in Vineyard Sound in winter are very slightly 

 smaller and apparently more slender in form than the northern spe- 

 cimens taken in summer and autumn, but seem to differ in no other 

 respect. Specimens from the Bay of Fundy agree perfectly with 

 Kroyer's figures referred to above, and with specimens received 

 directly from Prof. G. O. Sars and labeled by him T. inermis Kroyer. 

 Specimens sent several years earlier from the same locality by Prof. 

 Sars to the Smithsonian Listitution, as a specimen of the food of 

 Gadus virens, and labeled T. neglecta Kroyer, appear, however, to 

 be the same species, and do not agree with Kroyer's figures of T. neg- 

 lecta. It was an examination of these specimens which led me to 

 label specimens of our species T. neglecta ? for Prof. Verrill and Mr. 

 Whiteaves. 



In life this species is at once distinguislied from the Norvegica by 

 its much fainter coloring. It is exceedingly translucent, the sides of 

 the carapax and abdomen, and the bases of the cephalothoracic and 

 abdominal appendages are only slightly tinged with red. The nerv- 

 ous system and the peculiar sense organs, however, are brightly col- 

 ored as in the ISForvegica, and these together with the eyes are all 

 that is easily visible as the animal swims gracefully about near the 

 surface of the water.
