 of specimens furnished by Prof. Whitman, 

 dated July 30, 1890.

 more than one species); Mayer, 1903, p. 87

"One of the most common species of amphipod 

 on the southern coast of New England." 

 Holmes. In the Survey dredging recorded 

 from scattered stations throughout Vineyard 

 Sound: from Gay Head (especially common), 

 Robinsons Hole, Quicks Hole; recorded only 

 once for the Bay, near lower end. (See also 

 records for " Caprellidcs sp. sp. ".) Dredged in 

 i to 13 fathoms, chiefly at depths of less than 

 10 fathoms, and mainly on bottoms of sand, 

 gravel, and stones, where it is usually found 

 clinging to algae, hydroids, etc. Common like- 

 \vise among weeds, etc., growing on piles, and 

 on eelgrass; on one occasion taken in great num- 

 bers among Obclia geniculata, from a floating 

 plank in Vineyard Sound; Woods Hole, in 

 surface towj.

 month. J. P. McMurrich in Marine Biologi-

 Caprella linearis Linnaeus. 



Holmes, 1905, p. 526 (not listed for local waters); 

 M. J. Rathbun, 1905, p. 78 (not listed for local 

 waters). 



Dr. Kunkel thus identifies specimens taken by 

 Mr. Edwards in surface tow at Woods Hole, on 

 several occasions in October and November, 

 1905; likewise upon gulf weed and driftwood in 

 Vineyard Sound. 



Caprellidaz sp. sp. 



Species of this family (doubtless in the main 

 Caprella geometrica and ALginella longicornis) 

 were taken at many points in Vineyard Sound, 

 and occasionally in Buzzards Bay. It is nec- 

 essary to list them as undetermined since these 

 two species were at first confused in the records. 

 For this reason the relative distribution of the 

 two forms unfortunately can not be accurately 

 portrayed.

Woods Hole, on Bureau of Fisheries pier; Eel 

 Pond; Vineyard Haven on piles. Osburn. 

 Found on piles, among algae; also in eelgrass.

 6 We have followed Prof. Holmes in retaining this name, 

 to Caprella acutifrons Latreille. 



Tanais cavolinii Continued . 

 According to Bumpus this species was found 

 locally with eggs in various stages of develop- 

 ment early in August. Osburn records the 

 occurrence of unhatched eggs, as well as free- 

 swimming young, during the latter half of 

 July.
