MOLLUSCA OF INDIA. 57 
regular striation, less apparent on the last whorl; colour rich 
umber with a green tinge; spire elongate, sides nearly flat; 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; columellar margin sharply 
convex, then straight not solid, feeble truncation. 
Size: maj. diam. 6°5; alt. axis 26 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 L have from Pegu. 
Mr. Ossian Limborg was a particularly fine strong young man, 
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 explore 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 he returned in 
May 1877, with an interesting lot of Birds, Moilusea, and Insects, 
which he was instructed to pay 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 have been employed in some other parts of Burma.
