N. sublyrata Grun. — Valve constricted in the middle,
covered with parallel or sub-parallel striae, composed of distinet
puncta, 12 in 0,oi mm., reaching to the median line. Length
0,046 mm. Br. 0,oi mm. at the constriction 0,oo7 mm. — PL 35,

Mr. Grunow has sent me a sketch of his N. sublyrata,
which lives in brackish water in North America. The
American species is not so strongly constricted in the middle as
my specimen from Labuan. N. Cevlanensis Leud. Fortm.
(Diat. Ceyl. PL II, fig. 25) seemes to be nearlv related to this
species.
