183 
Etomology.— All of the material examined was collected near Sabang. Hence, Conopea 
sabangensis, from Sabang and the Latin -ensis, belonging to or from, literally Conopea from 
Sabang. 
Distribution. — Known only from the type locality near Sabang in the Verde Island Passage, 
Philippines. 
Species comparisons. — The species most similar in external appearance to C. sabangensis 
is C. willhearsii. The differences between the two species are described in detail in the description 
of C willhearsti, herein.

Diagnosis. — Shell elongated in basis, rostrum and carina; basis white, greatest depth beneath 
carino-latera, tapering to no depth at basal tips of carina and rostrum, or even slightly short of cari¬ 
na and rostrum basal tips; carina gently sloping fi'om summit to basal margin where it contacts host 
axis, about same length as carino-latus and latus width combined, shorter than rostrum; rostmm 
white, sloping gently from summit to basal margin where it contacts host axis, about 1.5 length of 
carina. 
Description. — Shell wall elongated along host axis, radii red, broadening near summits, 
summit even; basis white, sinuous margin along base of wall plates, edges raised with greatest 
depth beneath carino-latera, edges tapering to nothing at basal tips of carina and rostrum, or even 
slightly short of carina and rostrum basal tips, resulting in flat basis at extreme ends of shell; cari¬ 
na gently sloping fi'om summit to basal margin where it contacts host axis, about same length as 
carino-latus and latus width combined, shorter than rostmm, pink and white vertical and horizon¬ 
tal stripes; rostmm white, sloping gently from summit to basal margin where it contacts host axis.
