Tfie shell is stated by Blanford to be nearly allied to H. retifera, 

 Pfr., but to be distinguished from that species by its minute 

 u;nbilicus and by the form, number, and position of the internal 

 teeth, which in //. daghoha are small and compressed, bnt noi 

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

 The absence of parietal lamella?, however, indicates that the 

 afiinity of the present species must be looked for among sueli 

 forms as secessa, G.-A., and hilirata, 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 daghoha, together with p^'''''''f«'"'< and hidenticidata, might 

 belong to PhilalanJca, and as Lt.-Col. Godwin-Austen is ol 

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