LAND AND FEESHAVATER 



Jaw with a central projection. Radula similar to that of Bensonia, 

 with bicuspid laterals ; formula : — 



25 . 11 . 1 . 11 . 25 

 36 . 1 . 36 



The generative organs were broken and separated, but the ama- 

 torial organ was seen ; it is cylindrical, rather short, with a blunt 

 knob at the anterior end. A part of the male organ showed a 

 spermatophore, elongate and with serrated edges ; its form differs 

 from var. l-iirramensis, described above, in being narrower and longer 

 in proportion to its size. 



Of this banded species I have two specimens lent me by Mr. Blan- 

 ford, who received them from Major Wilmer, who, again, received 

 them from the collector. Colonel Sillery, of the 13th Regiment ; they 

 are marked "Afghanistan ? " I am informed since by Major Wilmer 

 that they were probably from Cherat. 



The largest is 21 mm. in major diameter of 6 whorls, and it 

 agrees with my Kurram example. 



I have also four fully-grown specimens and three young of this 

 same banded shell, obtained by my son, Captain R. A. Godwin- 

 Austen, of H.M. 54th Dorset Regiment, when quartered at Cherat, 

 in the Kuttak Hills. These are the largest examples I have seen, 

 and are very solidly built shells, one of which I now describe.

(Shell subturbinately depressed, narrowly perforate, of solid form : 

 sculpture, close irregular striation of growth, no other striation, a 

 young transparent shell of five whorls shows a fine network of 

 diagonal lines crossing nearly at right angles ; colour stony white, 

 with a narrow rufous band above the periphery following the suture 

 above on the inner whorls ; spire with rounded sides ; apex blunt ; 

 suture yellow ; whorls 6, close and increasing very regularly, the 

 last rounded and slightly descending at the aperture; aperture 

 lunate, very oblique ; peristome simple, rather solid ; columellar 

 margin solid, slightly reflected.

I have compared this with a typical specimen of B. tvynnci from 

 Murree ; they are evidently the same species. 



Blanford (P. A. S. Bengal, vol. xlii. pt. 2, 1880, pp. 197-199, 

 pi. iii. figs. 5, 5 a.) described the typical Murree form as follows : —
