H. SUBSEPULCHRALIS Crosse. Add to synonymy, CROSSE & 

 FISCHER, in Grandidier, Hist. Madag., Moll., t. 11, f. 1, la, Dec. 

 1889 ; and Journ. de Conchyl. 1890, p. 128. 



Form obscura C. & F. (pi. 62, fig. 37), Moll. Madag. t. 11, f. 2, 

 2a, 2b; Journ. Conch. 1890, p. 128. 



Form minor C. & F. (pi. 62, fig. 36). See H. sepulchralis RVE., 

 f. 147b. H. subsepulchralis ANGAS, P. Z. S. 1877, t. 80, f. 3. 

 CROSSE & FISCHER, Moll. Madag. t. 17, f. 7. 



Form nigropurpurea C. & F. This is H. subsepulchralis C. & F., 

 MolL Madag. t. 17, f. 8. 

 H. STRAGULUM Crosse & Fischer. PI. 64, figs. 64, 56, 66. 



This is closely allied to H. lamarei Mke. 



H. HOVA Angas. Add to synonymy, H. hova C. & F., Moll. Madag. 



t. 18, f. 2-5. 



In the second paragraph on page 25, read pi. 66, figs. 64, 65, in- 

 stead of " pi. 64." 



H. LAMAREI Mke. Add to synonymy, H. hova var. C. & F., I. c. t. 



18, f. 6, 6a. 6b, 7, 7a. 



Crosse and Fischer surmise that hova and lamarei will prove to be 

 one species. The narrower umbilical perforation of the latter seems 

 to me to separate them. 



*** 



H. ATROPOS Fer., according to Crosse and Fischer, belongs to the 

 group of H. omphalodes. 



H. NOVACULA Martens. Specimens lately received agree in all 

 respects with the one commented upon on page 33.
