AMPELITA (page 16.) 



Since the publication of the first number of the MANUAL for 1890, 

 Crosse and Fischer's Hist. Nat. Moll. Madagascar has appeared (See 

 note on page 65 of this volume) ; and also a review of the group of 

 H. sepulchralis in their Journal. 



AMPELITA SEPULCHRALIS Fer. 







Crosse and Fischer (in Journ. de Conchyl., xxx, p. 127) admit 

 and diagnose the following varieties of sepulchralis ; they are 

 mostly merely color-forms. 



Form sganziniana C. &. F. (pi. 64, figs. 58, 59). Depressed ; sub- 

 discoidal ; pale olive -brown ; spire subplaue ; inside of aperture and 

 peristome pale bluish, (see p. 21, this volume). This is the H. 

 sganziniana of Hist. Madag., Moll., plate 5, figs. 8-10. 



Form prceclara C. & F. Subdepressed, scarcely subdiscoidal, 

 chestnut-brown, aperture and peristome shining, vivid grayish-blue. 

 This is H. sepulcliralis var. g of Crosse & Fischer, Hist. Madag. 

 Moll., t. 17, f. 6. 



Form olivacea Pilsbry (pi. 64, figs. 62, 63). Subdepressed, sub- 

 discoidal, olive-yellowish, the earlier whorls very dark, pinkish or 

 purple ; apex whitish. This is H. sganziniana var. g of C. & F., 

 Hist. Madag., Moll., t. 12, f. 3, December, 1889. 



Form lethifera C. & F. (pi. 64, fig. 61). Subdiscoidal, depressed, 

 unicolored black ; aperture bluish-white inside, the peristome in- 

 tense brownish-black. H. sganziniana var., C. & F. in Hist. Madag. 

 Moll., t. 7, f. 3. 



Form fiinebris Martens (pi. 3, fig. 43-45). Larger than normal 

 sepulcliralis, the body-whorl malleated ; of a blackish-brown co]or, 

 with bands of papery whitish epidermis. 



Having again worked over the material examined by me when 

 preparing my monograph, together with a large number of additional 

 specimens received during the past year, and having studied atten- 

 tively the excellent work of Messrs Crosse & Fischer, I have arrived at 

 the following arrangement of forms of the H. sepulchralis group. In 

 the extent and perplexing inter-relations of the varieties, these 

 Helices may be compared to the H. californiensis group in America, 

 the H. peliomphala group in Japan, or the H. grayi group in 

 Australia.
