NEW DIATOMS. 
median line, and wanting in the middle of the valve, very delicately 
punctate, 6in., *01 mm. L. *057 mm. B. of lobes '012 mm., of 
isthmus, *004-*005 mm. Campeche Bay. 
(I have seen a similar form from the Sulu Archipelago, differing 
from the Campeche form by being about twice the size, and the 
striae being interrupted. — F. K.) 
6 N. Goesii. Cl. — Valves elliptical, with produced subcapitate 
ends. Striae distinct, 14 in. *04 mm, reaching median line parallel, 
slightly radiant at the apices, longitudinal striae slightly wavy. 
L. *07 mm. B. *024 mm. St. Bartholomew. 
7. N. (Brebissonia) (?) WeissflLogii. Grun. in “ Litt.” — Valve 
broad, rhombic, lanceolate, with obtuse ends. Central nodule linear, 
oblong, slightly constricted in the middle ; terminal nodules some- 
what distant from the ends of the valve. Striae radiating, punc- 
tate, 12.5-15 in. '01 mm, reaching the narrow median line. L. 
*085 mm. B. *03 mm. Campeche Bay. (This form was not 
unfrequent in Capt. Perry’s Colon gathering. — F.K.) 
8. Alloioneis (?) Griindleri. Cl. § Grun. — Valve broadly linear, 
oblong, with cuneate apices ; median line very excentric, somewhat 
arcuate, central nodule transversely dilated. Striae distinctly punc- 
tate, transverse, reaching median line. 11 in., *01 mm. L. '075 
mm. B. -028. Virgin Islands (very rare). Campeche Bay, Grun. 
Colon, Kitton. 
9. A. (Navicula?) Antillaxum. Cl. Grun.— Valve elliptic, 
oblong, median line a little excentric and curved. Striae composed 
of large distinct puncta, arranged in somewhat irregularly decus- 
sating oblique lines. The striae on one side of the valve nearly 
reaching the median line, leaving only a small area round the cen- 
tral nodule, on the other side the striae are much shorter, leaving a 
semi-lanceolate blank space. L. *12 mm. S. Bartholomew (rare). 
Gulf of Mexico, Grun. 
10. Navicula (Alloioneis ?) Kurzii. Grun. — Valve broad, lanceo- 
late, median line excentric, curved surrounded by an excentric blank 
space, which is irregularly enlarged in the middle, and becomes 
narrower at the ends. The rest of the valve is covered with 
granules like those on N. aspera, forming decussating oblique lines, 
and more narrow transverse ones 10-11 m. *01. The transverse 
lines reach as far as the median line, if seen under a high power. 
L. *09-*105 mm. B. *036 mm. Mangrove swamps, Elephant 
Point, East Indies. 
11. N. (Alloioneis?) curvinervia. Grun. — Valve oblong or lan- 
ceolate, with obtuse ends, median line excentric. Striae (costae ?) 
slightly radiating, noi reaching the median line, interrupted by two 
sharp longitudinal bends of the valve, smooth (under a very high 
power and favourable, delicately punctate), 8-9 in., -01 mm. L. 
•068--115 mm. Br. *022-028 mm. Mangrove Swamps, Elephant 
Point, E. Indies.
