»Niteschia (Perrya) Grundleri Grunow. Resembles N. 
Weissflogii, but the valve seems to be more eccentric, and is 
covered with parallel transverse punctate strix (12—14 in 
0,01 m.m.). The valves, which are more or less constricted 
in N. Weissflogii, are straight in N. Grundleri. Length 0,21 
—0,27 m.m. Hab. Campeche Bay (communicated by Dr. 
GRÖNDLER) — fig. 24 222 &« upper side, 8 lower side. — This 
beautiful diatom Nionde: also to the subgenus (or genus?) 
Perrya Kitton, but it approaches the other Nitzschie with 
very sharp keel by the more eccentric shape of the valve.»
