 DESCRIPTION OF A NEW GALEOMMA FROM BOMBAY. 



By J. R. LE B. TOMLIN, M.A. 



(Read before the Society, 8th December, 1920). 



Galeomma peilei n.sp. 

 Shell very similar in general appearance to G. indecora Deshayes, 

 which was found by Cuming at Masbate, under stones at low water, 

 but rather larger, longer, and more completely rounded at either 

 extremity, these being practically symmetrical ; less sculptured and 

 consequently more shining. The concentric lines of growth are 

 strongly marked in peilei^ but there is no trace of the strong radiating 

 strise so noticeable in indecora and in the British species turtoni, 

 and it is only under a high magnifying power that extremely fine 

 and close scratches, uniform over the whole surface, become visible. 

 The pitting is much less than in indecora, being close and strong in 

 the umbonal region, but decreasing in numbers and strength, and 

 finally disappearing a short way from the ventral margin. 



Length of type specimen, 13 mm. ; height, 6'5 mm. 

 . Habitat : Bombay, under stones at low-water (Lt.-Col. Peile, R.A.). 



Type : In British Museum. 



Superficially this species has a very similar appearance to our 

 British Galeojnma, but differs totally from it in sculpture. 



DESCRIPTION OF ANTIMITRA (?) HEWITTI n.sp. 

 FROM SOUTH AFRICA. 



By J. R. LE B. TOMLIN, M.A. 



(Read before the Society, 8th December, 1920). 



In the Journal of Malacology, xi, p. 31, pi. ii, f. 13, Smith figured 

 this species as Mitromorpha volva Sow. var., and gave an excellent 

 diagnosis, and it is curious that he did not describe it as specificaHy 

 distinct. 



The ribs are broader, flatter, further apart than in volva, and are 

 more widely spaced on the upper half of the basal whorl than else- 

 where ; there are four ribs on the penultimate whorl, and sixteen to 

 seventeen on the last, as against five to seven and at least twenty-one 

 respectively in volva, and the interstices show distinct axial sculpture, 

 consisting of fine raised lines very close together, with numerous
