GAtfESELLA. 197 



This bright coloration would naturally lead to the inference that 

 the animal is of arboreal habit and it is not, therefore, surprising 

 to find that Blanford records with regard to hariola a closely 

 allied form that it is found chiefly on trees. A feature, to which 

 no reference appears to have been made by any writer, is the 

 presence, not only on the protoconch but as far as the third whorl, 

 of densely crowded, minute pits, apparently arranged in obliquely 

 descending spirals. I have not observed these pits beyond 

 the third whorl in any specimen to which I have had access. 

 Mollendorff records specimens from Siam measuring 16*8 mm. 

 in diameter, thus considerably exceeding the type.

 Prome (Fea) ; Pyinthia near Mandalay (Nb'tling) Northern Chin 

 Hills (Watson, specimens Brit. Mus.). 



This form resembles G. capitium in colouring and marking 

 and appears to be distinguished purely by ite rounded periphery. 

 Its claim to varietal rank is even questionable, since connecting 

 links occur. Blanford collected at Puppa Hill an intermediate 

 form between the carinate stage and typical hariola, while von 

 Martens states that Notling brought home from Pyinthia, a place 

 28 miles from Mandalay. three specimens, one of which was 

 distinctly keeled, the second angulated, and the third with 

 completely rounded periphery. Grod win- Austen in his paper on 

 Spratt's shells states that two specimens were collected, one like 

 the type and the other keeled, which he called var. carinata of 

 W. T. Blanford's collection. I am not aware that Blanford ever 

 published this varietal name and it may be assumed that this form 

 is typical capitium. Nevill in his Hand List records specimens 

 from South India taken by Stoliczka. Although this naturalist 

 was admittedly careful I cannot help thinking that some error 

 must have crept in, and until confirmed by other collectors 1 

 think it advisable to discard this record.
