54 THE NAUTILUS. 
not glossy, vinaceous-russet fading to cinnamon-brown at the 
early whorls. First 3 whorls nearly smooth, the rest ribbed, 
the ribs straight, narrower than the slightly striate intervals, 
about 25 on the last whorl. The upper whorls are rather con- 
vex, the penult somewhat and the last strongly compressed 
laterally. The aperture is small, about one-sixth as long as the 
shell, piriform, the light brown peristome expanded and slightly 
reflected. Superior lamella rather small, marginal, oblique, not 
continuous with the spiral lamella, which is about a half-whorl 
long. The inferior lamella is situate high, converging to the 
superior; it ascends in a broad spiral a little past the dorsal line. 
The subcolumellar lamella is very deeply immersed, not visible 
in the mouth, but rather strong within the back. The principal 
plica is rather short, dorso-lateral, its lower end visible with 
difficulty in an oblique view in the mouth. There are quite 
short, subparallel upper and lower palatal plicae. 
The clausilium is quite broad, curved almost in a semicircle, 
passing without notch or excision into the filament. 
Length 13.6; diam. above aperture 2.4 mm.; length of aper- 
ture with peristome 2.3 mm.; 13 whorls.

The dull, strongly sculptured surface, small aperture and 
large number of whorls are the more salient external features of 
the species, and distinguish it from other Euphaedusae having 
similar palatal structure, such as C. planostriata Hde. It is 
named for the collector. 
A COLLECTING TRIP ON THE ISLAND OF OAHU, HAWAIIAN ISLANDS, 
BY THE GULICK NATURAL HISTORY CLUB. 
BY JOSEPH J. GOUVEIA. 
Karly Sunday morning on May the 25th, 1919, we started on 
the first trip planned by the Gulick Natural History Club. The 
purpose of this trip was to give the members of the club an 
opportunity to work on different lines.
