shorter and have the tarsus larger and rounder than in ¢rigonum, 
Pl. I, fig. 10e. The descriptions and figures are from specimens 
taken at Cold Spring Harbor on the north side of Long Island, N. Y. 
Ceratinella formosa, Banks. Ithaca, 1892. (Plate II, figures 5 to 5d.) 
This species was found by Miss E. B. Bryant at Long Island in 
Portland Harbor, Me., Sept. 11, 1904. It was in great numbers on 
the stones on the beach and flying by threads in the air. In size 
and color it resembles C. /eta. The males have the whole upper 
surface of the abdomen hard, while the females have only a hard 
spot across the anterior end. The cephalothorax and abdomen are 
both longer and less rounded than in /eta, and the sternum is 
narrower behind, measuring between the fourth legs one-third its 
length, while the sternum of /efa measures half its length. The 
epigynum has a triangular opening somewhat like that of “eta. The 
male palpus resembles that of C. dbrunnea; the process of the tibia 
is long and hooked, and the tube of the palpal organ is simple, 
with no tooth at the bend. This species lives among the small 
stones above high water on the beach, and runs much faster than 
the other Ceratinellas. Found at Gloucester, Mass. on beaches and 
one specimen in the Carter notch, White Mountains, N. H. 
Ceratinopsis auriculatus, new. (Plate II, figures 9, 9a, 9b.) 
1.5 mm. long and much like C. /aticeps. The colors are yellow 
and orange like the other species, with a little black on the head 
and ends of the palpi. The upper middle eyes are more than their 
diameter apart, and the lateral eyes are farther from them than 
they are from each other. Each pair of lateral eyes is raised on 
a little horn turned forward and projecting in a point beyond the 
eyes. The tibia of the male palpus projects upward and hooks 
forward. Seen from above it has three indistinct teeth in place of 
the two long ones of C. /aticeps. 
One male from Three-mile Island, Lake Winnipesaukee, N. H., 
May 29, 1906, Miss E. B. Bryant; one from Fitzwilliam, July 1907. 
Ceratinopsis alternatus, new. (Plate II, figures 6, 6a.) 
In general appearance this resembles the female C. interpres. 
The length is 2.6 mm. and the color is light orange brown with 
black between the eyes, but no other markings. The arrangement 
of the eyes is the same as in ivferpres, but the head is not quite 
as high and the back not as straight. The sternum is convex and 
large, and as wide as long, extending between the fourth coxe 
as wide as the coxe are long.
