ALYCELS. 269 



"I have compared this species with Abjams crispatns from tlie 

 Western Khasi, Garo Frontier, and with crispatus, var. i'rom the 

 Diyung- Valley, near Asaki {vide phite iv, figs. 1 & 2, J. A. S. B. 

 vol. xi, 1H71), and although a close ally, it differs considerably 

 from both, Ijeing much more conical, and with a diiierent 

 constricted area." (Gochvin- Austen.)

Original description: — " T, late umbilicata, depressa, subdis- 

 coidea, tenuis, subtilissime costulato-striata, corneo-hyalina ; spira 

 vix elevata, obtiisiuscula ; anfr. 4 convexi, ultimus latera inflatus, 

 prope aperturam strangulatus, auticeangustatus; apertura obliqua, 

 cireularis ; perist. simplex, album, subiucrassato-expansinsoulum, 

 marginibus approximatis, callo juuctis. — Operc. membranaceum, 

 multispirum. 



" Diam. 4], alt. 2| mill." {Pfeiffer.) 



iTrti. India: Simhi (»SVo//c/rrrt) ; Xaini Tal (OldJiam) ; Landoiir 

 (Hutton) ; Mussoorie, Kumaon ( Godvnn- Austen). 



Kobelt in ' Das Tierreich ' indicates Borneo as the habitat of 

 this species, evidently a lapsus. 



In Kumaon specimens Grodwin-Austen found the costulatiou 

 finer all over, and not so defined and distant near the sutural 

 tube, the general form of the tube the same, the swelling near 

 the constriction higher. Naini Tal specimens were of a similar 

 character.
