collected there. Certainly it is owing to its small dimen- 
sions, that only one specimen was collected by Mr. van Heurn.

*5. EUGLANDINA STRIATULA nov. sp. (fig. 1). 
Shell fusiform, thin, pellucid; yellowish-grey with many 
irregularly placed, longitudinal, brownish streaks. Whorls 
6'/,, convex; apex obtuse, the first whorl planorboid, the 
second shouldered, and rather flatly sloping outward. Near 
the end of the third whorl, a fine sculpture of spiral striae 
appears, decussated by faint folds. Gradually these folds, 
some of them bifurcating, become stronger; at the sutural 
border they are forming big grains. Aperture slightly oblique ; 
columella faintly convex above, then straight. 
Length 46'/,, diam. 18'/,, length of aperture 23, diam.

Type in the Leyden Museum. 
Lawa. Gonini-Expeditie. 
This species bears much resemblance to /. striata Müll. 
It can be distinguished by the whorls being more convex, 
and the suture more oblique than in the latter species. 
Also the height of the corresponding whorls is greater, 
and the folds are closer set and less coarse in this new 
species.
