250 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [544] 
ANURIDA MARITIMA (Guerin.) (p. 331.) 
This Podurid is very abundant on the under surfaces of large stones 
from high-water mark to about half tide, New Haven, Wood’s Hole, 
Nantucket; also on the coasts of Europe and Greenland. (Fabricius.) 
ARACHNIDA. 
CHERNES OBLONGUS Say. (p. 331.) 
Hagen, Record of American Entomology for 1868, p. 51. 
Under stones near low-water mark, at Wood's Hole, (8. I. S.,) several 
specimens were found together. This species is recorded from Florida 
and Georgia. I am not aware that it has been observed below high- 
water mark before. These specimens were identified by Dr. Hagen. 
TROMBIDIUM, species. (p. 331.) 
Several species of mites belonging to this or allied genera are found 
beneath stones near high-water mark, or even running over the fuci and 
rocks near low-water mark, but it is uncertain whether they become 
submerged by the rising ide or rise on its surface. 
BDELLA MARINA Packard, sp. noy. (p. 331.) 
Savin Rock, near New Haven, under stones between tides. 
“Elongated pyriform, of the usual form of the genus, the body being 
thickest at the insertion of the third pair of legs. Body with a few scat- 
tered hairs, especially toward the end. Palpi twice as long as labium, 
hairy toward the tip, four-jointed, basal joint not so long as second, 
third, and fourth conjointly; second a third shorter than third. Mandi- 
bles very acutely conical, projecting one-fourth their length beyond the 
beak, with about four hairs on the outer side; tips very slender acute, 
corneous. Legs rather hairy; fourth pair but little longer than the 
others. Claws consisting of two portions, the basal much compressed, 
subovate, with about six hairs on the under edge, and carrying a stout 
curved claw. Beak half as long as the body is wide. Length 2.5™™, 
“Tt differs from Say’s Bdella oblonga (‘from Georgia, under bark of 
trees, &c.) in its pyriform shape, the shorter first joint of the palpi, 
and much shorter beak.”—A. 8. P. 
PYCNOGONIDEA. 
PHOXICHILIDIUM MAXILLARE Stimpson. Plate VII, fig. 35, (p. 415.) 
Marine Invertebrata of Grand Manan, p. 37, 1853. 
Common in Vineyard Sound and the Bay of Fundy. 
PALLENE, species. (p. 421.) 
A small species, perhaps young, found upon piles of the wharf at 
Wood’s Hole, and dredged in Vineyard Sound, in 14 fathoms, off Tar- 
paulin Cove on Ascidians, and off Holmes’s Hole on Hydroids ; also off 
Watch Hill, Rhode Island, and New Haven.
