obtained living several times, and dead frequently. Acephala are 

 rather rare and small, but Bryozoa are abundant. Articulates 

 (Crustacea and Annelids) are well represented. But the great rich- 

 ness of this region lies in the Radiata. Of Echinoderms, the most 

 common is a Cidnris (nov. sp.), besides which there are several new 

 species of Echinidee and very interesting Asteridae and Ophiuridae. 

 Holotkurise are rather rare, except a new Psolus. Of corals, I have 

 eighteen new species, belonging principally to the families of Tur- 

 binolidas and Oculinidae ; the Eupsammidae are also represented by 

 two or three species, the Fungidas (a true Fungia) and the Millepo- 

 ridae by one each. The Madreporidae and Astraeidae are entirely 

 absent. There are also two or three species of Antipatlies, eight or 

 nine of Gorgonidae, several of Actinidae (some of them very abun- 

 dant), Hydroid polyps, sponges, and Foraminifera. As a general 

 rule, everything is of small size. There are no seaweeds. Some 

 animal remains are found whose presence is accidental, such as 

 sharks' teeth, bills of Cephalopods, shells of Pteropods, &c., which 

 have evidently come from near the surface, and also a considerable 

 number of bones of the manatee, most frequently i)ieces of ribs ; 

 for the occurrence of the latter I am not able to account, as the 

 manatee does not inhabit the open sea, and there are no currents to 

 bring the floating carcasses from its usual haunts in the shallow bays. 



From the third region the dredge brought up fewer though no 

 less interesting specimens, the chief of which is a new Crinoid 

 belonging to the genus Bourgueticrlnus of D'Orbigny ; it may even 

 be the species named by him B. Hotessieri, which occurs fossil 

 in a recent formation in Guadeloupe, but of which only small 

 pieces of the stem are known. I obtained half a dozen specimens 

 between 230 and 300 fathoms, unfortunately more or less injm-ed 

 by the dredge. 



The deepest cast made was in 517 fathoms ; it gave a very hand- 

 some Mopsea, a crab, an Ophiurian, and some annelids. 



The diiference of the deep-sea faunae of the opposite coasts of 

 Cuba and Florida is very marked, although the distance is so small ; 

 of all the corals, for instance, described by me from the coast of 

 Cuba, only two or three, and those in fragments, were found oil' the 

 Florida reef. 



The descriptions of the new species, with plates, are in prepara- 

 tion, and will be published, by the kindness of Prof. Agassiz, in the 

 next number of the illustrated Catalogue of the Museum of Compa- 

 rative Zoology of Cambridge. 



I am glad, also, to be able to say that Prof. Peirce, Superinten- 

 dent of the Coast Survey, has directed me to continue these researches 

 during the coming winter. — SilUman's American Journal, Nov. 1868.

The shore of south-western France inclines in a gentle slope to- 

 wards the west, and forms a vast submarine terrace, bounded by 

 deeps of more than 200 fathoms. The edge of this terrace, which is
