undetermined) and a number of specimens of Comatula Hayenii, 

 nov. sp. 



A Zoanthus, rather small, was obtained also, but, not having been 

 noticed when alive, it would be somewhat uncertain to determine. 



Hydroids : Antennularia triseriata, nov. sp.; Tlioa pulcliella, nov. 

 sp. ; Th. capUlaris, nov. sp. 



The Foraminifera had nearly all been washed out of the dredge ; 

 only the following were noticed: — Tcxhdaria con?Vrt,D'0. (very large) ; 

 Operculina [Spii'i^^na) incerta, D'O.; Rotalina cultrata, D'O.; and 

 Globigerina rubra, D'O. 



The total for this locality is therefore twenty-nine species, to 

 which a few ought to be added for the undetermined fragments of 

 Annelids. 



No di'edgings were had in mid-channel ; this part had been re- 

 served for the return trip ; but the unfortunate interruption of the 

 cruise prevented the execution of the project, at least for this season. 



The next casts were obtained off Havana in 270 fathoms, on May 

 24:th and 29th, on both days as nearly as possible on the same spot, 

 as the little that was obtained at the first date had given much 

 promise. 



The results of the two casts are combined below : — 



Articulates. — The Crustacea are not determined, but are of or 

 near the following genera : — Stenopus, Axia, Callianassa, OrcJiestia, 

 and Idotea, all living. Annelids : Marphysa tihiana, n. sp., and 

 M. antipathum, n. sp. Tubes and fragments of four or five other 

 species. 



Of the MoUusTcs the Gasteropods and Acephala have not yet been 

 determined, with one exception. 



The following genera are represented : — Mitra ?, Fusiis, Turbo, 

 Emarginidina , Dentalium, Nucida, and Spondylus, all dead ; Pedi- 

 C'ldaria decussata, Gould, and a very small Anomia, both living. 

 The Pteropods and Heteropods were all dead ; they are : — Hi/alea tri- 

 spinosa, affinis, D'Orh./gibbosa, Rang, and uncinata, Rang; Creseis 

 spinifera, Rang ; Cleodora ptyramidata, Per. & Les. ; Spirialis ros- 

 trata, Eyd. & Soul. ; and Atlanta Peronii, Les. Of Brachiopods 

 we obtained Terehratula cubensis, n. sp., and Terehratidhia CaiUeti, 

 Crosse ; both living and apparently abundant. The Bryozoa are : — 

 Farcimia cereus, n. sp.; Vincularia margaritacea, n. sp. ; Cellepora 

 reticulata, n. sp. ; C. sigillata, n. sp. ; Cauda retiformis, n. sp. ; Canda 

 cornigera, n. sp.; Idmonea Jleccuosa, n. sp. 



Radiata. — Echinoderms are represented by the following species: — 

 Spatangus (dead, fragments) ; Fibidaria (dead) ; Cidaris anmdosa, 

 Gray (probably, young, living) ; Tripneustes vcntricosus (living, very 

 young); Aster ias, sp. (very young, living); Opliiurians, at least 

 three species immature and difficult to determine ; Comatida brevi- 

 pinna, n. sp., living; Pentacriims, sp. (fragments of stem, among 

 which some appear quite fresh). 



Of Zoantharia the following were brought up : — Antipathes humilis, 

 n. sp. ; Antipathes filix, n. sp. ; Acantliogorgia aspera, n. sp. ; Gor- 

 gonia exserta, Ellis ; Siviftia exserta, Duch. & Mich. ; Hyaloncma 

 (spicules); Caryophyllia formosa, n. sp. ; Deltocyathus Agassizii,
