the peristome is vertical, not as in the present species horizontal. The 

 colouration, too, is peculiar, the fulgurate stripes above the peripheral hand 

 being much more open or more obtusely bent than in the narrow or more 

 acutely angled bands below it.

This remarkable species differs from most others in possessing a dis- 

 tinct tubular wing at the mouth which somewhat recalls the same feature in 

 Bt. Albersi, only the tube is more free and open. The only other species 

 possessing a second tube is S. Master si figured in the Conch. Indica, PI. V, 

 Fig. 1, but not described. In that species, however, the last whorl towards 

 the mouth is free and the peristomial tube less complete though longer 

 than in the present form. 



Steeptaxis bombax, Bs., PL XIV, Pig. 6. 

 I give an excellent drawing of this species kindly furnished to me by 

 Mr. W. T. Blanf ord. The species was originally described as BCelix bombax 

 from an immature specimen. The adult now figured was from the vicinity 

 of Maulmein. 



Amphidbomtjs Theobaldianus, Bs., PL XIV, Pig. 8. 

 A figure is here given of a perfect example of this rare shell, which 

 was described by Benson from an imperfect example. 



Geotbochtis Calcade^sis, Beddome, PL XIV, Pig. 7. 

 I also figm-e a specimen of this species (Beddome, J. A. S. B. 1870, 

 p. 18) forwarded to me by Mr. Bourdillon from Travankor. It is slightly 

 smaller than the type, measm-ing alt. 20, diam. major M'SO, minor 12'80, 

 aperturae alt. 11 -00, ejusdem lat. 8 - 00 mm.
