shorter and have the tarsus larger and rounder than in trigonum, 

 PI, I, fig. lOe. 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. lecta. 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 lata, and the sternum is 

 narrower behind, measuring between the fourth legs one-third its 

 length, while the sterrium of lata measures half its length. The 

 epigynum has a triangular opening somewhat like that of lata. The 

 male palpus resembles that of C. brunnca ; 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 laticeps. 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. laticeps. 



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 2.5 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 interpres, 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 coxas 

 as wide as the coxae are long.
