220 GLYPHIS. 



A regularly cancellated species, the altitude about one-third of 

 the length. The specimens before me are from Singapore. 



Sowerby has described a F. latiora, with the following descrip- 

 tion but no figure : " Quam F. singaporensis multo latiore. I omit- 

 ted a figure of this, not intending to distinguish it from the preced- 

 ing, than which, however, it is much broader" (Thes. p. 195). 



G. proxima Sowerby 2d. PL 63, figs. 15, 16. 



Less gibbous posteriorly and less suddenly inclined in front than 



F. ticaonica which it nearly resembles. The variety figured is marked 

 by green lines. (Soivb.)
