106 BULLETIN OF TOE 



(Spirillina) incerta D'O. ; Itotalina cultrata D'O. ; and Gldbigerina rubra 

 D'O. 



The total for this locality is therefore twenty-nine species, to which a fe\r 

 ought to be added for the undetermined fragments of Annelids. 



No dredgings were had in mid-channel ; this part had been reserved 

 for the return trip, but the unfortunate interruption of the cruise pre- 

 vented the execution of the project, at least for this season. 



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

 24th 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 of or near the 

 following genera: Stetwpus, Axia, Callianassa, Orchestia, and Idotea, all 

 living. Anneliils : Marphysa tibiana, n. sp., and M. anlipathum, n. sp. (see 

 description). Tubes and fragments of four or five other species. 



Of the Molluscs the Gasteropods and Acephala have not yet been deter- 

 mined, with one exception. 



The following genera are represented : Mitra ?, Fusus, Turbo, Emarr/inu- 

 lina, Dentalium, Nucula, and Spondylus, all dead ; 1 '< dicularia dt cussata, Gould 

 (see remarks), and a very small Anomia, both living. The Pteropods and 

 Heteropods were all dead ; they are : Hyalea trispinosa, affinis D'Orb., gib- 

 bosa Rang, and unclnata Rang ; Crcsds spinifera Rang ; ( 'h <»/nr<i pyramidata 

 Per. and Les. ; Spinalis rostrata Eyd. and Soul.; and Atlanta Peronii Les. 

 Of Brachiopods we obtained Terebratula cubensis, n. sp., and Terebratulina 

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

 Farcimia cereus, n. sp. ; Vincularia margarilacea, n. sp. ; Cellepora reticulata, 

 n. sp. ; C. sigillala, n. sp. ; Cauda retiformis, n. sp. ; Cauda cornigera, n. sp., 

 Idmonea Jlexuosa, n. sp. (see descriptions). 



PvADiATA. Echinoderms are represented by the following species : Spa- 

 iangus (dead, fragments) ; Fibularia (dead) ; Cidaris annulosa Gray (prob- 

 ably, young, living); Tripneusles ventricosus (living, very young) 5 Asterias, 

 sp. (very young, living); Ophiurians, at least three species, immature and 

 difficult to determine; Comatula brevipinna, n. sp., living; Pentacrinus, sp. 

 (fragments of stem, among which some appear quite fresh). 



Of Zoantharia the following were brought up: Antipathes Jiumilis, n. sp. ; 



Aniipalhes filix, n. sp.; AcanlJiogorgia aspera, n. sp. ; Gorgonia exserla Kllis; 



Swiftia exserla Duch. and Mich. ; Hyalonema (spicules) ; Caryophyllia for- 



\ n. sp. ; Dellocyathus Agassizii, n. sp. ; Slylaster complanalus, n. sp. ; 



Errina glabra, n. sp. ; Errina cochleata, n. sp. ; Crypthelia Peircei, n. sp. ;
