DESCRIPTIONS OF SOME NEW SHELLS FROM THE NEW HEBRIDES 

 ARCHIPELAGO. 



BY C. F. ANCEY. 



Endodonta i?i tenuiscripta Ane. 



Shell ranch depressed, lenticular, very sharply keeled at the peri- 

 phery, thin, not much shining, of a somewhat silky appearance, 

 openly but very widely umbilicated. Spire convex, apex obtuse, 

 with ") regularly and slowly increasing whorls, barely convex and 

 furnished with a linear and appressed suture, the last one slightly 

 impressed above and below the very acute keel, slightly convex 

 above, more so beneath. Umbilicus circular, exhibiting all the volu- 

 tion (1-j mill, wide), surrounded by a very obtuse angle. Aperture 

 rather oblique, securiform, somewhat sinuous, very much angular at 

 the end of the carina, not deflexed in front. Margins distant 

 scarcely connected by a very thin shining deposit. Sculpture very 

 fine, consisting of oblique and very fine crowded lines of growth. 

 Color fulvous, with numerous fine and irregular stripes of a brown 

 tint, larger on the last whorl. 



Greater diam. fii, less. 6, height 3 mill. 



Island of Mallicolo, New Hebrides (E. L. Layard). 



This shell is evidently related to my Put aid Glistoni, described 

 several years ago from the same group of islands. According to 

 Mr. Pilsbry's new arrangement, this should perhaps be rightly located 

 in Endodonta with the species now considered, unless it may eventu- 

 ally prove to belong to Flammulina. E. teimi^i-fi/iln is a very 

 beautiful little shell, recalling the Hawaiian E. Anr/A<->/ which is 

 very much like it, but wanting internal lamina?. It looks like a 

 small Trochomorpha and especially Pararhytida on a very small 

 scale, but is perhaps nearer to Crosse's Hi'lix trirhocoiiu'i, from New 

 Caledonia. 



From its ally, Patula Glissoni, found in the island of Vate, New- 

 Hebrides, it may be easily distinguished from its larger size, much 

 more acute keel, different style of color, planulate whorls and other 

 differences. 



Melania vatensis Am-. 



Shell imperforate, turrited, somewhat shining, rather solid, fulvous 

 with irregular and more or less interrupted longitudinal brown 

 stripes and dots and lighter suture on the two last whorls. Ground 

 color frequently more obscure at the base. Spire long, pointed,
