90 GLESSULA, NON-PENINSULAR INDIA TO INDO-CHINA. 



A much more slender species than A. tenuispira Bens., 

 (a variety of which also abounds in parts of Pegu), though 

 there are signs of a passage. The present appears to replace 

 A. tenuispira in Arakan and Bassein. Mr. Benson, to whom 

 I sent a specimen, observes that it is intermediate between 

 A. tenuispira and A. hastula Bens. (Blanf.) 



Col. Beddome gives the localities, Assam; Arakan; Garo 

 and Naga Hills; Burma, He remarks that " Blanf ord's 

 types and all the specimens I have seen of this, are young 

 shells, with fragile, unformed lips. They fit well with young 

 of tenuispira. Blanford himself mentions that there are 

 signs of a passage, and it would 'certainly not be advisable to 

 consider it a good species without seeing specimens with adult 

 lip."

Shell slender, turrite, thin, yellow-corneous, glossy, 

 weekly striatulate, and having vertical grooves at unequal 

 intervals; this sculpture is most evenly developed just below 

 the suture. Under the compound microscope glimpses of ex- 

 cessively weak close spiral granule-lines may be seen in places. 

 Outlines of the spire nearly straight, a trifle contracted near 

 the apex. Whorls 9 1 / 4, moderately convex, separated by a 

 deeply impressed simple suture. Aperture a little oblique; 

 outer lip thin; columella rather long, regularly concave, 

 truncate at the base. Length 19, diam. 6.6, length of aper- 

 ture 6.5 mm.

The later whorls are decidedly longer than in G. tenuispira 

 and its immediate allies. The specimens were received from 

 Nevill under the name used above; they may possibly be 

 Glessula no. 80 of his Handlist, since they seem related to 

 G. subfusiformis.
