2. Carcharodon rondeleti Miiller & Kenle.— 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. 



Schools of this species are said to be occasionally noticed in the open 

 sea from Monterey southward. 



3. Cetorhinus maximus (Linnajus) Blamville.— 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.) Blamville. — 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 (Li.) Bl.iiuville. 



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 Shaj-k. 



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. Ceplialoscyllium laticeps (Dum^ril) Gill. — Ground Shai-k. 



The occurrence of this species at San Pedro has been already noticed 

 by us. At Santa Barbara it is, next to Triads 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 laevis (Eisso) Gill. 



Two specimens of this si)ecies have been obtained by us at Monterey. 

 One of them, a female, taken March 2C, 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 hinmdus {vulgaris, canis, etc.), on the 

 Pacific coast, is very interesting.
