Boise. Still another small one was caught August 15. The species is 
often taken while fishing for weak fish. No large examples have been 
seen by me, but Captain Chamberlain reports one of 5 or 6 feet. This 
is the u shovel-nose shark ” of the fishermen, although not the u shovel- 
nose ” of the books. 
The hammer head shark was not found by Professor Baird in 1854, 
but the true “ shovel-nose ” was common. 
99. Reniceps tiburo (Linn.). 
Zygoma tiburo Baird, Rep. Fisk, N. J., 1855, 39; Ninth Ann. Rep. Smith. Inst., 
1855, 353. 
Professor Baird obtained one specimen of this shark arid the fisher- 
men took several more. Singularly enough we failed to see this species, 
but the u hammer-heap shark,” which was not seen by Professor Baird, 
was taken frequently by us. 
100. Carcharias obscurus (Le Sneur). Man-eating shark. 
Carcliarias cceruleus Baird, Ninth Ann. Rep. Smith. Inst., 1855, 352. 
Abundant in the bay. Young individuals, caught with hooks, July 
29, and measuring 21J to 24 inches in length, still bear the umbilical 
scar. Examples 7 feet long have been seen. Recently, while the bay 
was visited by large schools of menhaden, sharks were unusually 
abundant. 
This is the u man-eating shark ” of Somers Point. A specimen weigh- 
ing 150 pounds was reported July 23, and during the same week Charles 
Steelman landed one weighing 200 pounds. 
101. Mustelus cams (Mitchill). Dog shark. 
Mustelus canis Baird, Ninth Ann. Rep, Smith. Inst., 1855, 353. 
Very common and very annoying to anglers. A small individual was 
seined at Ocean City, August 1. No adults have been observed. 
This is known as u dog shark ” at Somers Point.
