THE NAUTILUS. 15 
chestnut along the upper middle whorls just below the suture. In 
most specimens the first three or four whorls are broken off, leaving 
only about two that show the sharp costulation. 
3. Melania hastula Lea. 
One young specimen, apparently referable to this species. 
4, Neritina zigzag Lam. 
5. Neritina cornea L. 
6. Neritina turrita Chemn. 
All of these have a wide distribution throughout the East Indies. 
7. Melampus fasciatus Desh. 
Color patteru very variable. A variety, “javanica,” occurs in 
Java (Mousson, p. 46). 
8. Pythia striata Reeve. 
This agrees more perfectly with the mainland form than with the 
Javan P. pyramidata, yet for geographical reasons it may be likely 
that this is a localized variety of the latter. The two species seem 
to be very close. 
9. Cassidula mustellina Desh. 
Quoted from the Philippines to Java. 
10. Amphidromus enganoensis Fulton. Ann. and Mag., series 6, Vol. 17, p. 71. 
11. Trochomorpha Hartmani Pfr. 
Originally described from Java. The largest of three specimens 
collected measures: height 11:5, greater diam. 35, lesser diam. 29 
mm. 
12. Planispira Aldrichin.s. PI. 2, figs. 4, 5. 
Shell depressed, deeply umbilicate, low conic above, rounded be- 
neath; acutely carinated at periphery. Whorls 4%, the last not 
descending, excavated above and below the keel. Aperture some- 
what oblique, subtriangular. Lip simple above, expanded below, 
basal lip reflexed partly over the umbilicus. Ends of lip connected 
by a faint callous. Sutures not impressed. Light chestnut brown, 
a darker space above and below the keel and above the sutures. 
Sculpture of faint wrinkles of growth, covered with very faint, re- 
volving striz below the keel; under the glass showing a minutely 
pitted-granular surface, the granulation more pronounced below the 
keel. 
Alt. 15, greater diam. 28, lesser diam. 23 mm.
