neio Deep-sea Mollusca. 371 



I do not agree with Kiener and Tiyon in considering this 

 form a variety of the common R. cui-virostris. The points of 

 difference referred to by Sowerby and E-eeve appear to be 

 persistent; they consist of (1) the shorter body-whorl, (2) the 

 longer and straighter canal, (3) the broad brown band beneath 

 the suture. Judging from the description and figure, R. luteo- 

 stoma of Angas, also considered by Tryon a variety of 

 curvirostris^ appears sufficiently distinct. 



Puncturella [Cranopsis) asturiana (Fischer). 



Punctiirella {Cranopsis) asturiayia (Fisclier), Watson, Gaster. 'Chal- 

 lenger' Exped. p. 4-5, pi. iv. tig. 4; Pilsbrv, Man. Conch, vol. xii. 

 p. 241, pi. xxvi. ligs. 30, 37; Dall, Bull. Mus. Coiup. Zool. Harvard, 

 vol. xviii. p. 404. 



Hab. Bay of Biscay, 480-670 fathoms (i^iscAe?-); W. Indies, 

 85-640 fathoms {Dall) ; off Gulebra Island, West Indies, in 

 390 fathoms (^Challenger'') ; off west coast of Ceylon, lat. N". 

 8° 35' 45", long. E. 81° 17' 45", in 609 fathoms {'Investi- 

 gator''). 



Only a single small specimen 7 millim. long was obtained. 

 It agrees exactly in every detail with the West-Indian 

 example dredged by the ' Challenger,' and I feel no doubt 

 with regard to the correctness of this identification. 



Dentalium qiiadrapicale, Sowerby. 



Dentaiium quaclrapicale (Hanley, MSS.), Sowerby, Thes. Conch, vol.iii. 

 p. 103, pi. ccxxiii. fig. 61 ; Conch. Icon. vol. xviii. pi. vii. fig. 46. 



Huh. Lat. 9° 34' 57" N., long. 75° 36' 30" E. (depth 

 4( 6 fathoms, bottom green mud, temperature 40° F.) ; off the 

 coast of Travancore, South India. 



'i he types of this species are said to have come from 

 Cochin. The specimens obtained by the ' Investigator ' are 

 somewhat larger than the shell figured by Sowerby, the 

 largest specimen having a length of 40 millim. 



Dentalium magnijicum. 



Testa magna, crassa, mediocriter curvata, postiee sensim attenuata, 

 antics oblique truncata, undique costis temiibus numerosis, striis 

 transversis crenulatis, instriicta ; fissura angusta, longitudine 

 varia. 



Longit. 115 millim,, diam. max. 1.5. 



Uah. Lat. 8° 40' N„ long. 81° 27' 35" E., 637-800 fathoms 

 (bottom green mud, temperature 41°-42°-25 F.) ; off Trin- 

 coraalee, east coast of Ceylon.
