6 NON-MARINE MOLLUSCS OF SURINAM, 
* 6. BUGLANDINA SURINAMENSIS nov. sp. (fig. 2). 
Shell fusiform, rather solid, corneous, with irregularly 
placed, longitudinal brownish streaks on the last two whorls. 
Whorls 6, a little convex; apex obtuse, the second whorl 
not shouldered, but slightly rounded. On the fourth whorl 
a sculpture of fine spiral striae and irregular faint folds 
appears. On the last two whorls these folds, some of them 
bifurcating, become a little more distinct; they are how- 
ever not strongly developed; at the suture they are forming 
a crenulated border. Aperture vertical; columella concave. 
Length 32, diam. 13'/,, length of aperture 16!/,, diam. 
8 m.M. 
Type in the Leyden Museum. 
Post Groningen. van Heurn, 1911. 
I could not identify this shell with any species of 
Euglandina recorded from the north and north-east of 
South-America. It is easily distinguished from young spe- 
cimens of the preceding species by the shape of the apex 
and by the sculpture of the last whorls. 
Some other specimens of an Huglandina, collected in 
the environs of Paramaribo, one of them apparently sub- 
fossil, are in too bad a condition to identify them. Possibly 
they might also belong to this species. 
Till now the genus Euglandina had not been recorded 
from Surinam. No doubt a careful investigation of the 
molluse-fauna of this colony will bring to light more species 
of this South- and Central-American genus. 
* 7, CONULUS ERNSTI Jouss. 
Ernstia ernsti, Jousseaume, Mém. Soc. Zool. de France, 
Tome II, 1889, p. 251, Pl. IX, f. 17, 48. 
Post Groningen. van Heurn, 1914. 
Only one specimen of this little shell has been collected, 
agreeing with the description and figures given by Mr. Jous- 
seaume. It is not necessary to substitute the generic name 
Conulus by the new name Ernstia, the Echinoderm genus
