Vineyard Sound, on Pennaria tiarella. Wilson. 

 Bureau of Fisheries pier, Eel Pond. Morgan. 

 Abundant in Eel Pond. Cole. Confined to 

 shoaler water than Tanystylum, and Anoplodac- 

 tylus, and for this reason not so often taken in 

 the Survey dredgings. One specimen dredged 

 near Gay Head, at Blue Wing station 45*. 



Carries eggs in July, August, and September.

 maxillare); Bumpus, i&gSb (Phoxichilidium 

 maxillare); Cole, 1901; 1906. 



Piers at Woods Hole and Vineyard Haven; found 

 on piles between tides and down to consider- 

 able depths, usually among hydroids, algae, 

 ascidians, etc.; a very common species, es- 

 pecially abundant in colonies of Eudendrium, 

 upon the hydranths of which it feeds. Cole. 

 Dredged almost exclusively in the eastern half 

 of Vineyard Sound, where it is common; 

 taken once off Penikese; 7 to 17 fathoms, 

 chiefly on sandy and stony bottoms. Survey. 



Fish Hawk stations: 7522 (i), 7527(4, i with eggs), 

 7528 (i), 7532(i), 7537 (i) 7538 (2), 7538 bis 

 (about 12), 7541 bis ( i male with eggs), 7549 bis

 7758 (2 females, 3 males), 7759 (i male with 

 eggs), 7760 (2 males with eggs, i female). 



Phalarope station: 63 (i). 



Carries eggs from July to September 30. Morgan. 

 Larvae probably parasitic in some hydroid. 

 Family EXDEID^E. 



Endeis spinosus (Montagu). 



Cole, 1910, p. 193. 



A species of Endeis [Plwxichilus] which was found 

 abundantly, in association with Obelia dicho- 

 ioma, upon floating gulfweed in the western 

 part of Vineyard Sound, can not be separated 

 from this European species, though it differs so 

 markedly in habitat. Collected July 5, 13, 

 September 4, 19, 1904, October 15, 1905, 

 August 22, 1906, October 8, 1906. (Collected 

 by V. N. Edwards and J. A. Cushman, identi- 

 fied by L- J. Cole). Adult males (many bear- 

 ing eggs), females and young taken. 



Family PYCNOGONIDID.*;. 



? Pycnogonum littorale (Strom). 



E. B. Wilson, 1880, p. 469.' 



No local records, though this region is included 

 within the known range of the species. It 

 probably occurs, however, only in the deeper 

 water outside the limits of the Survey. 



o Specimens from points designated by an asterisk (*) were identified by Dr. I,. J. Cole. 



b Norman^ Journal Linnsean Society, vol. 30, 1908, p. 204) has substituted the earlier name A naphia (Say, iSji)for Anoplcr 

 dactylus (Wilson, 1878). Since, however, Say's descriptions and figures were far from perfect, and it is by no means certain 

 that the forms are congeneric, Dr. Cole has thought it advisable to retain the later name.
