 vexo ; apertura obliqua, subovato-lunata, intus opalina, fascia

This shell perhaps resembles the Ceylonese H. Chenui more 

 than any Indian shell ; but it is much more openly perforate, 

 the aperture somewhat differently shaped, and the sculpture, 

 though very similar, shows marked distinctions ; the shell is 

 larger and far more angulate at the periphery, especially near 

 the mouth. 



From the young shell of H. hasileus the present form may 

 be recognized by its very different sculpture, its much shorter 

 axis and lower spire, by the last whorl being far less inflated 

 below, and consequently by the lower margin of the peristome 

 being less convex ; it is a much thinner shell, and the colora- 

 tion is much browner. 



The sculpture is peculiar : the striae of growth are crossed 

 by impressed spiral lines, and by short, shallow, oblique 

 furrows at right angles to the striae, and meeting the spiral 

 lines at an acute angle. 



The locality at which alone this shell has been found is 

 south of Peermede and on the west side of the Travancore 

 hills, in Southern India.

iEGERiA, Fabr. 



Dr. Staudinger, in his l Catalog der Lepidopteren ' (1871), 

 has omitted Walker's species, 2E. agathiformis, Cat. Lep. Het. 

 viii. p. 34. n. 54 (1856). Even supposing this species to be 

 identical with any other previously described, it ought not to 

 have been left out of a professedly complete catalogue of 

 European Lepidoptera ; he has also omitted to place jE. aqri-
