 stripes as in furcillatus ; the lip and columella pink.

Authenticated specimens of Theobaldianus in the British 

 Museum are identical with specimens of moniliferus received 

 from Gould himself.

Prof, von Martens, in his i Ost-Asien Moll.' p. 80, makes 

 this species a variety of Schomburgki ; he also considers the 

 type of glaucolarynx to be an abnormal form, and thereupon 

 drops Dohrn's name altogether, naming the small form of 

 glaucolarynx as Schomburgki, var. fasciata, Mart. Until more 

 material has been examined I do not think one can say that 

 the typical glaucolarynx is abnormal ; the type is 48 millim. 

 in length, and there is in the British Museum a specimen 

 45 millim. long, only 3 millim. less. The small form which 

 Martens considers the normal form of glaucolarynx I think is 

 better classed as a variety, but not of Schomburgki, which I 

 consider to be quite distinct from glaucolarynx.

Like typical glaucolarynx, but only about 35 millim. in 

 length, and with a spiral cream-coloured band just below the 

 periphery. I was unable to see the type of Perrieri myself, 

 but Dr. Jousseaume, to whom I sent a specimen of the above 

 for comparison, writes that he is unable to separate Perrieri 

 from this variety.
