MOLLUSOA OP INDIA. 57 



rosular striation, less apparent on the last whorl : colour rich 

 umber with a green tinge ; spire elongate, sides nearly dat ; apex 

 somewhat attenuated, blunt ; suture shallow ; whorls 11, increasing 

 very gradually in size, sides flattened, the last with a sign of a keel 

 above the aperture ; aperture rather narrow, ovate, straight on 

 inner margin ; outer lip flatly convex ; coluraellar margin sharply 

 convex, then straight not solid, feeble truncation. 



Size : maj. diam. G'5 ; alt. axis 20 mm. 



This single specimen was among the shells collected by Mr. O. 

 Limborg in 1877, and I name it after him ; it has remained un- 

 described ever since. The species is of delicate form, and quite 

 distinct from any Glessula 1 have from Pegu. 



Mr. Ossian Limborg was a particularly fine strong young mnn, 

 son of a Swedish minister, and a keen naturalist. He arrived in 

 Calcutta in the winter of 1876, and called on me one morning at 

 the Museum anxious to collect and ex])lore anywhere. I took him 

 up, and together with Lord Tweeddale, Dr. John Anderson, 

 Superintendent of the Indian Museum, and Mr. Wood Mason, we 

 fitted him out with all that was necessary and sent him to 

 Moulmein to collect in Tenasserim, from whence be returned in 

 May 1877, with an interesting lot of Birds, Mollusca, and Insects, 

 which he was instructed to pav particular attention to. Very much 

 material was obtained on the Peak of Mooleyit and its vicinity ; of 

 the mollusca he brought back were some very interesting and 

 valuable species preserved in spirits. I am sorry to say he suffered 

 much from malarial fever and had to return to Europe, otherwise 

 he was to liave been emplo} ed in some other parts of Burma.
