2. Carcharodon rondeleti Miiller & Henle.—Man-eater Shark. 
A large individual of this species was lately harpooned at the whaling 
station of Point Carmelo, near Monterey: Its jaws, now in the posses- 
sion of Mr. A. C. Keating, a druggist at Monterey, are about two feet 
across. i 
Schools of this species are said to be occasionally noticed in the open 
sea from Monterey southward. 
3. Cetorhinus maximus (Linneus) Blainville.k—Basking Shark; Ground Shark. 
An individual of this species, 31 feet in length, was taken March 25 
by the whalers at Monterey, and another somewhat larger on March 
26. Several others were noticed, but only two were secured. We are 
told that eighteen or twenty years ago several of them were taken at 
Monterey, since which time few or none have been noticed in the bay. 
4. Carcharhinus glaucus (L.) Blainville.—Blue Shark. 
A young individual of this species, taken in San Francisco Bay, is in 
the museum of the California Academy of Sciences. A ‘“ Blue Shark” 
is found in the open sea along the southern coast of California, but I do - 
not know whether it is this species. 
5. Galeorhinus galeus (L.) Blainville. 
As already noticed, this species is the most abundant shark of South- 
ern California. It is common at Santa Barbara, and I am told is not 
unfrequently taken at Monterey. | 
6. Galeocerdo tigrinus Miiller & Henle.—Man-eater Shark. 
As already noticed by us, jaws of an individual of this species were 
seen by us at San Diego, near which place the animal was obtained. 
7. Cephaloscyllium laticeps (Duméril) Gill.—Ground Shark. 
The occurrence of this species at San Pedro has been already noticed 
by us. At Santa Barbara it is, next to Triacis semifasciatus, the most 
abundant of the sharks. It is there taken daily in the lobster-pots set 
for the “ craw-fish ” (Palinurus interruptus). Its habit of inflating itself, 
when caught, by swallowing air, is very remarkable. 
8. Pleuracromylon levis (Risso) Gill. 
Two specimens of this species have been obtained by us at Monterey. 
One of them, a female, taken March 26, had the young about 8 inches 
long, each of them connected by a long umbilical cord to a placenta 
which is attached to the uterus. The occurrence of this shark, in con- 
nection with its relative, Mustelus hinnulus (vulgaris, canis, ete.), on the 
Pacific coast, is very interesting.
