 Colour pale ochraceous, with a greenish tinge. Spire conic, sides 

 nearly flat; apex blunt. Suture shallow, with a thread-like 

 liration. Whorls 8, narrow, sides very slightly convex below the 

 liration, flat from that to the suture. Aperture sernilunate,

 umbilicum reflexum, itittis 2 dentibus palatalibus munitum.

 (Blanford.} 



Hab. South India : Patchamullay and Kalryenmullay Hills 

 (Foote). 



The shell is stated by Blanford to be nearly allied to TI. retifera, 

 Pi'r., but to be distinguished from that species by its minute 

 umbilicus and by the form, number, and position of the internal 

 teeth, which in H. daghoba are small and compressed, but not 

 lainelliform, and are situated very near the edge of the peristome. 

 The absence of parietal lamellae, however, indicates that the 

 affinity of the present species must be looked for among such 

 forms as secessa, Gr.-A., and bilirata, Blanf., rather than retifera, 

 Pfr. The position of the teeth near the peristome induced the 

 present writer in 1900 to include the species in Sesara, but the 

 late W. T. Blanford, in a letter dated Sept. 23rd, 1900, pointed 

 out that daghoba, together with pirrieana and bidenticulata, might 

 belong to Philalanka, and as Lt.-Col. God win- Austen is of 

 the same opinion as regards daghoba, I have included it here.
