124 BULLETIN OF THE 



these bones is now made to the bottom, nor has been since these coasts 

 have been settled upon by white men, we have a proof that the deposit 

 due to other causes is very blow, since the dredge finds the bones still 

 lying loose on the bottom. 



The other vertebrate remains are teeth of sharks and eggshells of 

 skates. Living fishes were obtained in only two instances at about 100 

 fathoms : one was a Phycis ; another, a small fish of the Lophioid 

 family, not yet determined. 



The Crustacea are rather abundant, but, the specimens not having 

 been fully examined, we can only give now an imperfect list of the 

 genera represented: Stenorhynchus, Inachus, Amathia, Pisa, Mithrax, 

 Lupa, Ethusa, Pilumnus, Dromidia, Eupagurus, Paguristes, G'a/ut/tea, 

 Thysanopoda, Alima, Garidine, &c. 



Of the Mollusks, the most abundant in individuals are the Brachio- 

 po<K particularly Terebratida cubensis, Pourt. (Bulletin Mus. Comp. 

 Zool. No. 6), of which over 1,200 specimens were collected, and Wald- 

 heimia floridana, now sp., a little less common. The Terebratulina 

 Gailleti, common on the coast of Cuba, was found very rarely on the 

 coast of Florida, and always dead. The Gasteropods are more numer- 

 ous than the Acephala, but, as well as the latter, are represented by 

 small species. The largest ones are the Voluta junonia, and a Trochus 

 of about the same size. As the Mollusks of the collection have not 

 yet been determined, a list of the genera must suffice for the present : 

 Murex (2 species), Fusus, Nassa, Pedicularia, Cassis, Dolium, Pleu- 

 rotoma, Voluta, Marginella, Natica, Vermetus, Trochus, Monodonta, 

 Delphinida, Scissurella, Fissurella, Rimula, Emarginulina, Pileopsis, 

 Dentalium, Chiton, Marsenia, Eolis ; — Cucullea, Pectunculus, Nu- 

 cula, Leila. Lucina, Mactra, Necera. 



The only ones among these abundant in individuals are a Pleuro- 

 toma, a Marginella, a Vermetus, a Monodonta, and a Cucullea. 



Bryozoa are also frequent in individuals ; but there are less species 

 apparently than on the coast of Cuba in similar depths. 



The Radiates Conn perhaps the most interesting part of the collec- 

 tion, being represented in many cases by now or little known genera. 

 The Echinoderms have not vet been determined, with the exception of 

 the Ilolothurians, of which only three species are found ; one of them, 

 Cuvieria opercidata, nov. sp., is tolerably common; the others are a 

 Thyonidium] and another which the imperfection of the specimen has
