certainly not less remarkable as regards the crustaceans. The 

 richness of the fauna in both species and individuals would 

 never have been suspected by one accustomed only to the 

 meagre fauna of the shallow waters of the south coast of New 

 England. 



In regard to the mollusks and echinoderms, it is here 

 sufficient to quote a few sentences from Professor Verrill's 

 article. He says : — " Of MoUusca about 175 species were 

 taken. Of these, 120 species were not before known to occur 

 on the southern coast of New England ; about 65 are addi- 

 tions to the American fauna ; of these about 30 are apparently 

 undescribed. The known species now added to our fauna have 

 mostly been described by G. O. Sars, Jeffreys, and others 

 from the deep waters of the European coast and the Mediter- 

 ranean." "The Starfishes and Ophiurans were exceedingly 

 abundant and beautiful at all the stations ; and many species 

 not known previously on our coast were taken, several of 

 which appear to be undescribed, while others were known 

 only from Northern Europe or from the deep waters off 

 Florida. Many of the species have only recently been 

 obtained from the northern fishing-banks off Nova Scotia. 

 One new species of Archaster {A. americaruis) was particu- 

 larly abundant, several thousands of specimens having been 

 taken ; but the two largest and most beautiful species of this 

 genus were Archaster Agassizi (new) and A. Florce. Of 

 Odontaster Mspidus over 100 were taken." There are 

 thirty-two species in the partial list of echinoderms given, 

 four of which are described as new. 



A preliminary notice of the Crustacea obtained from this 

 interesting region is noAv in type for the ' Proceedings of the 

 National Museum ' for 1880 (pp. 413-452) ; and I here give 

 only a very brief statement of the most interesting results 

 there brought out, with full descriptions of the new forms. 



Among the Brachyura were Hyas coarctata^ Cancer horea- 

 lis, and Geryon quinquedens, which were known from further 

 north; but with these there were Collodes depressus^ Eujjro- 

 gnatharastelUferaj Bathynectes longispina, and Acanthocarpus 

 Alexandria species previously know"n only from the Straits 

 of Florida. There were also new species of Ethusa and 

 Lamhrus, genera quite new to our waters. The Euprognatha 

 occurred in the greatest abundance at nearly every station, 

 many thousands of specimens often being taken at a single 

 haul. 



Among the Anomura occurred Homola harhata and Latreil- 

 Ua elegans (which represent families heretofore unknown on 

 this side of the Atlantic), a beautiful species of Lyreidus, De
