fLamna cornubica — Continued. 
A shark believed to be of this species was taken 
at Wauwinet, Nantucket, July 29 (year?). — 
Howard Ayers, in Marine Biological Labora- 
tory card catalogue. Not otherwise recorded 
for this region. 
Carckarodon carcharias (Linnaeus). Man-eater 
shark.

Smith, 1873, p. 576; Jordan and Evermann, 
1896, p. 50; H. M. Smith, 1898, p. 89; Ken- 
dall, 1908, p. 7. 
Buzzards Bay in neighborhood of Woods Hole, 
rare. Recorded by Baird in 1871; two speci- 
mens taken in local trap in 1903 (June 17 and 
2 S)- 
Parasites: Cestodes (Linton) — Dinabothrium sep- 
taria, Pkyllobothrium sp. Copepods — Echthro- 
galeus denticulaius (Verrill and Smith); Pan- 
darus sinuatus (C. B. Wilson). 
Family Cetorhinidas. 
tCetorhinus maximus (Gunner). Basking shark, 
bone shark. 
Jordan and Evermann, 1896, p. 51. 
A specimen, apparently of this species, was 
taken in a trap at Menemsha Bight August 16, 
1906. It was reported as being 12 to 14 feet 
long. This shark was identified by Prof. I. A. 
Field from a description given by Mr. Edy 
Flanders. It was called a “bone shark” by 
the fishermen. Another large specimen taken 
at same point in 1908. — Edwards. 
Family Squalid^. 
Squalus acanthias Linnaeus. Dogfish (called 
“horned” or “spiny” dog locally, to distin- 
guish it from Mustelus) .

Buzzards Bay and Vineyard Sound; compara- 
tively scarce in the neighborhood of Woods 
Hole at present, a fact in striking contrast to 
its pestiferous abundance at some other points 
of the coast. Formerly so numerous locally 
that it was the chief source of the “fish guano ” 
produced at the Woods Hole factory. Abun- 
dant at Nantucket, according to Sharp and 
Fowler. Taken in May, and again in smaller 
numbers in October; not taken locally in the 
Squalus acanthias — Continued. 
intervening months. — Edwards. Caught in 
traps, seines, and gill nets. 
Always full of well-developed embryos during 
the run. — Edwards. Embryos from Balfour’s 
“B” to 30 mm. in length; also young “pups” 
6 inches long, July 2 to 17, 1895. — W. A. Locy, 
in Marine Biological Laboratory card cata- 
logue). 
Food: In May largely ctenophores. — Smith. In 
order of frequency: Ctenophores ( Pleurobrachia 
in great numbers, squid, Nereis, fishes (hake, 
herring). — I. A. Field.

Common everywhere on sandy bottoms in the 
deep and shoal waters of Vineyard Sound; in 
Buzzards Bay having a much more restricted 
distribution. Present from April to Octo- 
ber. — Edwards. Taken in traps, fyke nets 
and seines. Likewise dredged by the Survey 
in from 6 to 17 fathoms, particularly in the 
western end of Vineyard Sound ; in the Bay 
dredgings only recorded from stations near the 
lower end.
