It lias quite the form of P/alippiana, but is one third smaller, has 

 one whorl less and the last whorl is comparatively a little more 

 stretched. It appears to be a constant form and will probably 

 deserve a separate specific name. 



ITab. Common at the Farm-caves near Moulmein on limestone 

 hills. 



The animal of CI. Philippiana is black with a greenish tinge on 

 the posterior part of the body, which is covered with rather coarse 

 warts ; the pedicles are moderately elongated, pinkish, slightly 

 swollen at the tips which bear the small eyes centrally ; tentacles 

 very short, but distinct ; foot moderately elongated, strong, posteri- 

 orly obtusely pointed. 



The clausilium is thin, white, somewhat broader than the ex- 

 panded, and also white, portion of the columella, on which it reclines 

 when the animal protrudes out of its shell. When closed, the exter- 

 nal edge of the clausilium rest on the palatal folds ; this appear 

 to have the object of preventing the shell being closed hermetical- 

 ly, that is, to admit a little air even when the animal has retracted 

 the body in the shell, which it can do far behind the clausilium. 



Tl}e mantle has a free entire edge, and is internally somewhat 

 thickened, especially on either side of the pulmonary orifice. At 

 the place of the labial fold the edge is simply grooved. Cor- 

 responding to the columellar rib the groove is much stronger 

 and deeper, extending with free raised edges to the mantle- 

 margin. The lower (or anterior) of these lamellar edges is se- 

 micircularly enlarged, and towards the end folded over ; it se- 

 cretes the columellar fold, with its internal laminar projection for 

 the support of the clausilium. The upper (or posterior) edge is 

 smaller and evidently secretes the clausilium ; it becomes folded 

 over the former when the animal protrudes out of its shell. 



As regards the internal structure there is nothing very distinct 

 from the anatomy of the Helicid^:, as may be seen by a comparison 

 of figure 8 on pi. vi, and the explanation accompanying it. 



The pulmonary cavity is narrow and long, the mantle for- 

 ming it being rather thick and of a deep pinkish black colour. The 

 kidney is of a large sub-triangular form, and one portion of it 

 almost entirely envelopes the heart. The mouth is small and the
