Reported by Smith from the stomach contents of 
the sea bass ( Centropristes ), tautog and sea 
robin. 
Hexapanopeus angustifrons (Benedict & Rath- 
bun). 
Benedict and Rathbun, 1891, p. 373 ( Panopeus 
angustifrons, sp. nov.); M. J. Rathbun, 1905, 
p. 7. 
Vineyard Sound, off East Chop, in 1887 (Fish 
Hawk stations 1205-1208); Nantucket Sound; 
Buzzards Bay. — Rathbun. Buzzards Bay at 
Fish Hawk stations 7612*, 7628*, and 7639* 
(1907 repetitions), where this species was taken 
in company with Neopanope texana sayi. Also 
at Phalarope stations 84*, 144*, 145*, 147* (all 
likewise at Buzzards Bay). 
? Rhithro panopeus karrisii (Gould). 
Verrill and Smith, 1873, p. 547, 313, etc. ( Pano- 
peus harrisii); S. I. Smith, 1879, p. 37 ( Pano- 
peus harrisii); Benedict and Rathbun, 1891, 
p. 378 ( Panopeus harrisii ); M. J. Rathbun, 
1905, p. 8. 
Rocky shores, “occasionally met with under 
stones, but lives rather higher up [than dcpres- 
sus or sayi] toward high-water mark; ” found in 
brackish, even nearly fresh, water. — Smith. 
No definite local records, though this region 
lies within the known range of the species. 
Family Pinnotherid^E. 
Pinnotheres ostreum Say. Oyster crab. 
Verrill and Smith, 1873, p. 346, 438, etc.; M. J. 
Rathbun, 1905, p. 5. 
Naushon, 1886. — Rathbun. The female of this 
species is the familiar “oyster crab,” and is 
doubtless frequently taken locally, though but 
one definite record exists. The male is free 
swimming, and has been taken at the surface 
in Vineyard Sound. — Smith. 
Pinnotheres maculatus Say. Mussel crab. [Chart 
1 x 9- J

Rathbun, 1884, p. 766; Bumpus, 1898b; M. J. 
Rathbun, 1905, p. 5. 
Buzzards Bay, in 1887 (Fish Hawk station 1215). — 
Rathbun. In Survey dredging, only recorded 
from Vineyard Sound; absence from Bay rec- 
ords may, however, be due to our failure to ex- 
amine the mussels. Males taken in tow at the 
local pier in July, October, and December*. — 
Edwards. Like the preceding species, this crab 
lives commensally in bivalve mollusks. It is 
common in Mytilus edulis, Modiolus modiolus, 
and Pccten magcllanicus . R. Rathbun states 
that from a bushel of the last species, taken 
off Newport, nearly a pint of the crabs were 
taken; while single specimens of Modiolus, 
examined by members of the Survey, have 
been found to contain as many as seven or eight 
crabs. The male, as with the preceding spe- 
cies, is free swimming, though sometimes met 
with in the hosts. 
Fish Hawk stations: 7530 (2, with eggs, in Modi- 
olus), 735s (1 in Mytilus), 7556 (many in My- 
tilus), 7561 (many of both sexes in Modiolus), 
7563 (in Mytilus), 7564 (in Mytilus), 7565 (in 
Mytilus), 7583 (1 large female, from Modiolus), 
7598 (3 from Modiolus), 7679 (female with eggs), 
7681 (3), 7732 (1), 7733 (4), 7737 (2 females and 
1 male), 7758 (1). 
Egg-bearing females observed by F. P. Gorham 
from July 9 to August 29. — Bumpus.

Adults dredged in Buzzards Bay, young taken 
at the surface in Vineyard Sound. — Smith. 
According to Smith this is by far the commoner 
of the two local species of Pinnixa. Woods Hole , 
Naushon. — Rathbun. Buzzards Bay, at Fish 
Hawk station 7614 (1907 repetition), 2 speci- 
mens. — Survey. This crab inhabits the tubes 
of Chaetopterus pergamentaceus and of Amphi- 
trite ornata. One of the Pinnixas, believed to 
be this species, is fairly common on a shoal be- 
tween Ram Island and Devils Foot. Four 
specimens were taken here with 13 Chaetop- 
terus by J. F. McClendon and C. B. Bennett. 
Pinnixa sayana Stimpson. 
Verrill and Smith, 1873, p. 546, 367, etc. (Pin- 
nixa cylindrica); S. I. Smith, 1882, p. 250; M. 
J. Rathbun, 1905, p. 6. 
Vineyard Sound and Buzzards Bay (dredged), 
living in the tubes of certain large annelids. —
