With regard to Keeve's remark that he had seen the type 

 of this speeies and that it was " identical with the shell sub- 

 sequently dedicated to Kiener by Doumet," tliere must have 

 been some mistake. The type from Dr. Gray's collection is 

 now in the Museum, and it belongs unquestionably to the 

 same species as speciosa^ Hve., and is therefore distinct from 

 P. Kieneri. I presume that Reeve's statement must have 

 misled both Tryon and Weinkauff in associating it with tiie 

 latter. The brownish spots between the nodules on the keel, 

 as represented in Gray's figure, are hardly visible in the shell 

 itself. This, however, is probably a fault in the colouring, 

 so as to give the keel a nodulous appearance. Tiiis view of 

 the case is supported by the fact that in the brief description 

 by Gray he describes the shell as '' white, whorls keeled," 

 and does not mention the existence of any brown spotting. 



Pleurotoma {Ancistrosi/rinx) iravancorica. 



Testa fusiformis, turrita, sordide albida, epidermide tenuissima grisea 

 induta ; anfractus normales 7, supra oblique et concave tabulati, 

 supra medium carina dentata tenui sursum erecta instructi, infra 

 carinam recti, contracti, lineis incrementi tenuibus striati, ulti- 

 mus antice recte et longe rostratus, oblique striatus ; apertura 

 cum canali longit. totius | paulo superans ; labrum tenue, supra 

 carinam ad suturam profunde sinuatum. 



Longit. 40 millim., diam. 10. 



Hah. Off coast of Travancore, lat. N. 9° 34' 57", long. E. 

 75° 36' 30", in 406 fathoms. 



The unique specimen has the nuclear whorls broken away, | 

 and consequently they cannot be described. In general ; 

 appearance it much resembles P. cedo-nulli^ Reeve, from ; 

 Panama. In tlie latter the dentate keel is at and not ahove ' 

 the middle of the whorls, the dentations stand out more hori- . 

 zontally, the upper part of the whorls is less concave and \ 

 bears a fine spiral liration. The body-whorl is also carinate a 

 little below the dentate periphery.
