I 9 ° 5 > P- 77 - 
Woods Hole. Described by Mayer from a number 
of specimens furnished by Prof. Whitman, 
dated July 30, 1890. 
Caprella geometrica Say.® 
Verrill and Smith, 1873, p. 567, 316, etc. ( Ca- 
prella sp. — Verrill’s records perhaps refer to 
more than one species); Mayer, 1903, p. 87 
(C. acutifrons)', Holmes, 1905, p. 526; M. J. 
Rathbun, 1905, p. 77 ( Caprella acutifrons). 
“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 “Caprellidce sp. sp.”.) Dredged in 
1 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- 
wise among weeds, etc., growing on piles, and 
on eelgrass; on one occasion taken in great num- 
bers among Obelia geniculata, from a floating 
plank in Vineyard Sound; Woods Hole, in 
surface towf.

Eggs observed in the brood pouch, July 15; ma- 
turing embryos found toward the end of the 
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 gulfweed and driftwood in 
Vineyard Sound. 
Caprellidce sp. sp. 
Species of this family (doubtless in the main 
Caprella geometrica and LEginella 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. 
Fish Hawk stations: 7545 (few), 7551 (many), 
7552 bis ?, 7553 bis (1), 7557, 7560 (many), 
7568, 7581 (few), 7585 (1), 7591 (1), 7598 (many).

Amphipods unidentified. Fish Hawk stations: 7580, 7678, 7718, 7728. Phalarope and Blue Wing 
stations: 21, 156.

Woods Hole, on Bureau of Fisheries pier; Eel 
Pond; Vineyard Haven on piles. — Osbum. 
Found on piles, among algae; also in eelgrass. 
Tanais cavolinii — Continued. 
According to Bumpus this species was found 
locally with eggs in various stages of develop- 
ment early in August. Osbum records the 
occurrence of unhatched eggs, as well as free- 
swimming young, during the latter half of 
July.

to Caprella acutifrons Latreille.
