' Conchylien Cabinet ' on account of its imagined re- 

 semblance to the erect stem or trunk of the yew-tree. 



Species 26. (Mus. Cuming.) 



Pletjrotoma Javaka. Pleur. testd elongato-fusiformi, 

 albci, fulvo longitudinattter nebulosd ; anfractibus 

 convexiusculis, superne concavo-depressis ; canali 

 elongato, flexuoso, transversim striato ; labro tenui,

The Java Pleurotoma. Shell elongately fusiform,

 pressed ; canal long, flexuous, transversely striated ; 

 lip thin, widely emarginated.

 Murex Javanus, Linnaeus. 

 Murex tornatus, Wood. 



Hab. ? 



This shell is by no means uncommon in an imperfect 



state, white, without the least indication of colour. 



Species 27. (Mus. Cuming.) 



Pleurotoma olivacea. Pleur. testd fusiformi, oli- 

 vaced, anfractibus valde tuberculosis, striatis quasi 

 funiculatis, superne lavibus; canali amplo ; labro 

 postie'e sinuato,fauce slriatd. 



The olive-brown Pleurotoma. Shell fusiform, olive- 

 brown ; whorls strongly tuberculated, and striated 

 as if they were corded, upper part smooth ; canal 

 large ; lip sinuated at its junction with the last 

 whorl, interior striated. 



Sowerby, Pro. Zool. Soc, 1833, p. 136. 



Pleurotoma funiculata, Valenciennes MSS. ; Kiener, 

 Icon., pi. 16. f. 4. 

 Hab. Salango and St. Elena, West Columbia; Cuming. 



Panama, Gulf of Nicoya and Western Coast of 



Mexico (from mud in four to seven fathoms depth) ; 



Hinds. 

 I am not surprised that Kiener should have failed to 

 recognise this species ; it is exceedingly difficult to 

 identify a shell by description alone. 



Species 28. (Mus. Cuming.) 



Pleurotoma nodifera. Pleur. testd fusiformi, turritd, 

 cinereo-fulvd ; anfractibus medio angulatis, supra un- 

 guium lavibus, infra striatis; angulo nodulis oblongis, 

 albidis, obliqtiis, uniseriatim cincto ; labro subinflato, 

 rotundato, sinu lato ; canali flexuoso. 



The knobbed Pleurotoma. Shell fusiform, turrited, 

 ashy yellow ; whorls angular in the middle, smooth 

 above and striated below ; angle ornamented with 

 a single series of oblique white oblong knobs ; lip 

 rather inflated, rounded ; sinus broad ; canal flex- 

 uous.

Kiener, Icon., pi. 12. f. 1. 



Pleurotoma Javana, Enc. Me"th., pi. 439. f. 3. 



Hab. Straits of Malacca (from mud in eighteen fathom: 

 depth) ; Hinds. 

 I have a very compactly operculated specimen of thi 

 shell in my possession. The operculum is horny 

 rather thin, and fits closely to the aperture.
