steamer was under weigh. In this way a great number of surface 

 species were collected, and a large proportion of them are additions 

 to the fauna of our coast. Many of these species belong to genera 

 previously known only from much farther south, or from the eastern 

 or southern Atlantic, while quite a number are undescribed. 



August 29, on and near Cultivator Shoal {k), where the surface 

 temperature of the water was 62°, the following were taken : Trachy- 

 nema digitale A. Agassiz, Pleurobrachia rhododactyla Agassiz, species 

 of Sagitta and Aidolytus, several species of Copeopod Crustacea, 

 Calliopius Icevhisculus Boeck (among floating rock-weed), the young 

 of some Brachyuran in the zoea and megalops stages of growth, and 

 a species of 31otella (?). 



East of George's Bank, in latitude 41° 20' to 30', longitude 63° 

 to 63° 30', September 14, during the day, many species were taken, 

 but as they all occurred, with many additional species, on the follow- 

 ing day, it is not necessary to enumerate them separately. 



On the evening of September 14, from nine to ten o'clock, still east 

 of the Bank (m), in latitude 41° 25', longitude 63° 55', while the sur- 

 face temperature was 65°, the following forms occurred : Pleuro- 

 hrachia sp. ; a species of Salpa in abundance ; several species of 

 Heteroi^ods and Pteropods, among the latter Sjnrialis Gouldii 

 Stimpson, and species of Styliola j a species of Sagitta,' a species of 

 Sapphiri^ia and a great many other Copeopods ; species of Syj^eria, 

 Phrosina^ and of another allied genus ; a species of Thysa)iopoda, 

 which was beautifully phosphorescent ; young Brachyura in the zoea 

 and megalops stages, and the young of some Macrouran. 



September 15, on the same line of soundings, in latitude 41° 25', 

 longitude 65° 5' to 30', the temj^erature of the water varying from 66° 

 to V0°, but most of the time at the latter point, very many species 

 occurred, and among them the following: Physalia pelagica Lamarck 

 (Portuguese man-of-war), Cestum Veneris Lesueur (?), Stomolophus 

 meleagris Agassiz, Charyhdea periphylla Peron and Lesueur, Pelagia 

 cyanella Peron and Lesueur ; species of Salpa and Sagitta in great 

 abundance ; Lepas pectinata Spengler and L. fascicularis Ellis and 

 Solander ; two species of Sapphirina and many other genera of Coj^e- 

 opoda ; species of Oxycephalus, Platyscelus, Pronoe^ Anchyloinera^ 

 ThyropuSy Phronima (?), and Hyperia; Calliopius Imviiiscidus Boeck, 

 common among floating rock-weed ; species of Lucifer and Mysis ; 

 Latreiites ensiferus Stimpson, JVautdognq)sus mimdus Edwards, and 

 Neptunus Sayi Stimpson among gulf-weed, and the latter frequently 

 seen swimming at some distance from the sea-weed ; three species of 

 Heteropods and ten species of Pteropods, all new to our coast.
