150 BULLETIN OF THE 



of Urechinus closely allied to Urechinus naresianus, and several of the 

 rarer species of Starfishes, — Archaster, Porcellanaster, Luidia, Astro- 

 gonium, Porania, Pteraster, and Hippasteria, — were fonnd to extend 

 far into deep water; and beyond 1,000 fathoms, off George's Bank, 

 we found several fine specimens of Brisinga, as well as three or four 

 species of the remarkable deep-sea Holothurians belonging to the or- 

 der of Elasmopoda; among the Crinoids, Comatula Sarsii? and a few 

 specimens of lihizocrinus. Although the line to the eastward of Charles- 

 ton, S. C, was commenced off the very home of the Scutellse and other 

 Clypeastroids, it is remarkable that not a single Mellita or Clypeaster 

 was dredged up, either on that line or the line run in the axis of the 

 Gulf Stream as far as Cape Hatteras. Echinarachnius off George's Shoal 

 was found to extend to a much greater depth, living specimens having 

 come up in the trawl from a depth of 524 fathoms. 



But few Annelids were collected, a few specimens of Nemerteans, and 

 of Calymne ; one of the large Eunicidse, the tubes of which, sometimes 

 fully fifteen inches in length, often filled the bottom of the trawl when 

 dragging on muddy bottoms, was specially numerous. 



A number of species of Cephalopods, mainly Northern species already 

 found in shallower waters by the United States Fish Commission, w^ere 

 brought up, many of them from considerable depths. The Gasteropods 

 and Acephala were represented by many of the species collected by the 

 ''Lightning" and "Porcupine," and by the United States Eish Com- 

 mission. 



Among the Crustacea the most characteristic types were the gigantic 

 Pygnogonidse, a species of Willemoesia, a couple of species of Gnatho- 

 phausise, Scalpellum, and large Amphipods. 



Among the Fishes a large collection was made, mainly of Macrouridse, 

 including a few new genera, which will be described by Mr. Goode, of the 

 United States Fish Commission. We found cod, extending to a depth 

 of over 300 fathoms (off George's Shoal). Myxine and Lophius were 

 brought up from 360 fathoms, as w^ell as Sebastes norvegicus. A species 

 of Phycis, from a depth of 233 fathoms, was found to be electric, giving 

 quite a strong shock to Commander Bartlett and myself It is a small 

 species, about nine inches in length, of a light ashy violet color, with dull 

 yellowish spots along the sides. 



The absence of siliceous and other sponges in the collections made 

 during this summer is very striking, and although the number of speci- 

 mens of certain species was often very great, yet the continental fauna? 

 of the northern part of the east coast of the United States is poor when
