Reported by Smith from the stomach contents of

Hexapanopeus angustifrons (Benedict & Rath- i 



bun).

 angustifrons, sp. nov.j; M. J. Rathbun, 1905, 

 p. 7. 



Vineyard Sound, off East Chop, in 1887 (Fish i 

 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). 



? Rhithropanopeus hanisii (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 dcprcs- 

 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^. 



Pinnotheres ostreum Say. Oyster crab. 



Verrill and Smith, 1873, p. 546, 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 

 119.] 



Verrill and Smith, 1873, p. 546, 309, etc.; R. 

 Rathbun, 1884, p. 766; Bumpus, iSgSb; 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 Pecten 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), 7555 (i in Mytilus), 7556 (many in My- 

 tilus), 7561 (many of both sexes in Modiolus), 

 7563 (in Mytilus), 7564 (in Mytilus), 7565 (in 

 Mytilus), 7583 (i large female, from Modiolus), 

 7598 (3 from Modiolus), 7679 (female with eggs), 

 7681 (3), 7732 (i), 7733 (4), 7737 (2 females and 

 i male), 7758 (i). 



Egg-bearing females observed by F. P. Gorham 

 from July 9 to August 29. Bumpus. 



Pinnixa chcetopterana Stimpson.

P- 5- 

 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 speciesof Pinnixa. Woods Hole, 

 Naushon. Rathbun. Buzzards Bay, at Fish 

 Hawk station 7614 (1907 repetition), 2 speci- 

 mens. Survey. This crab inhabits the tubes 

 of Choetopterus pergamentaccus 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 Chaitop- 

 terus by J. F. McClendon and C. B. Bennett. 



Pinnixa sayana Stimpson.

 nixa cyiindrica); S. I. Smith, 1882, p. 250; M.
