Size: Major diam. 23 o ; minor diam. 13*0. 



It is almost impossible to get a perfect shell. In pi. xxiii, 

 fig. 4, there may be seen a portion of thin internal side wall of the 

 shell (S) adherent to the visceral sac and left or rather torn off 

 when the shell was removed. 



Sarama kcmpi, n. sp. 

 (Plate xxiii, figs. 6, 7, 8 ; pi. xxiv, figs. 6, 7.) 



Upper Rotung, Abor Hills. 



Shell thin, glassy, depressedly globose, scarcely perforate. 



Sculpture strong, regular, somewhat wavy, longitudinal stria- 

 tion, coarser on the base. 



Colour with animal in shell very dark greenish brown, animal 

 removed sienna brown. Spire flat convex. Suture shallow. 

 Whorls 6, regularly increasing, apical closely wound and flat. 



Aperture laterally ovate, sub-vertical. 



Peristome very thin, as also on the columellar margin which 

 is very oblique. 



Size: Major diameter i8'25 ; alt. axis 7*25 mm. 



This species in its anatomy is nearest to Sarama kala, G.-A., 

 of Sikkim, but I do not remember seeing before shell lobes at 

 all like these, especially the left shell lobe. 



Mr. Kemp's field note of this species dated 6-1-12, is as 

 follows: — "Common under leaf stems of plantain. When fully 

 "extended anterior part of body very dull purplish grey with 

 "darker grey eye-stalks. Hinder part of foot and mantle lobes 

 "salmon-pink speckled with a paler shade ; under surface of foot 

 ''rather darker salmon-pink with a yellowish tinge along the 

 ■'edges. The margin of the sole in dorsolateral view, salmon 

 ''pink. Body of animal, seen through shell, horn-coloured, in 

 "one case with a few large pale flecks on the outer whorl." 



Animal in spirit : — Both the right and left shell lobes are pecu- 

 liarly long, rounded and thickened, in typical species of the genus ^ 

 these are thin and flat, in this case they do not appear to broaden 

 out when the animal is alive; they are connected with a band which 

 overlaps the edge of the peristome and these with the dorsal lobes 

 are conspicuous against the dark colour of the adjacent parts. The 

 animal in this state is so well described above by Mr. Kemp, after 

 whom I have the pleasure of naming it, that one made from a spirit 

 specimen would be no improvement. The gland at the extremity 

 of the foot has an overhanging hooked lobe — the visceral sac is 

 very blue black with 4 white spots on the periphery of the last 

 whorl. It is this, seen through the transparent sienna brown shell, 

 which gives it such a fine colour. 



Genitalia. — The male organ is small, a short rather thick 

 sheath from the end of which a long retractor muscle is given ofl', 

 there is a very short and b^ack epiphallus, and an equally short 

 flagellum in which a sperraatophore forming is seen, the vas
