TESTACELLA. 1 1 



T. PECCHIOLII, Bourg. PL 1, figs. 41, 42. 



Shell rather narrow, elongate, slightly convex, corneous and 

 rugosel}- striated above ; whitish and slightly concave within ; 

 apex minute, recurved, acute, smooth ; columella deflexed, very 

 slightly arcuate. Length, 5 mill. 



Italy, frequent near Florence. 



This is T. haliotidea of many of the older Italian authors, 

 according to Bourguignat : it appears to me to be very nearly 

 allied to T. bisulcata. 



T. BECCABII, Issel. PL 1, figs. 43, 44. 



Shell trigonally ovate, oblique, anteriorly arcuate, posteriorly 

 acuminate, flattened and concentrically rugosely striated above, 

 corneous, yellowish within ; apex acute, slightly curved, smooth, 

 columella incurved, whitish. Length, 6*5 mill. 



Ripoli, near Florence, Italy. 



Marchioness Paulucci, who was unable to obtain specimens 

 at the above locality, found there numerous individuals of T. 

 Pecchiolii, and she conjectures that it is an abnormal form of the 

 latter. 



?T. DIKRANGENSIS, Godwin-Austin. PL 1, figs. 18, 19. 



Shell dextral, ovate, very flat, solid, the lines of growth well 

 marked, with a dark brown epidermis, the apex cap-shaped, 

 rather produced, and much curved. 



Major diameter 0'50 inch, minor diam. 0'25 inch. 



Animal not seen. 



Assam. 



Two shells were found in a damp low piece of forest near the 

 Dikrang River, close under the village of Pachitah. u The shell 

 is a peculiar form, the body-whorl spreading out and overlapping 

 in front, giving the shell a limpet-like shape. Without a knowl- 

 edge of the animal it is ve^ difficult to say in what genus it 

 should be placed, but it is probably a Helicarion form. The 

 shell, however, so much resembles Testacella, that I have placed 

 it temporarily in that group." 



T. VAGANS, Hutton. 



Shell auriform, subspiral, depressed, imperforate ; elongately 

 oval, the sides nearly parallel, the anterior end rather broader 

 than the posterior ; columellar margin callous ; apex subspiral,
