The Blue Shark, Penn. iii. 109. Yarr.ii.381. Rarior. 
The ‘‘Marrazo” of the fishermen is probably some species of this genus ; 
though it may be also merely the following (Lamna cornubica, Cuv.) full-grown, 
or of large size. 1 have not seen a specimen. 
The ‘‘ Tubaréo”’ is another large-sized Shark, which I have not seen. From 
the teeth being described as small, it may prove, perhaps, to be the Basking 
Shark (Selache mazima, Cuv.).

** Squalus cinereus, Gm.” Cuv. Rarior. 1 have not seen the specimen, but depend 
on Miss Young’s identification of one brought to her in May 1835, with “‘/e 
Perlon, Lac.”, during my absence from Madera. The head of this specimen is 
at present in the Society’s Museum. 
Centrina Salviani, Will. Hist. Pisc. p. 58. t. B. 2. 
A single female specimen only has occurred, measuring 3 feet 3 inches in 
length. It contained six young ones, from 3 to 3} inches long; they were al- 
together white, except their fins and tail; the teeth unfortunately were not yet 
formed. ‘Their dorsal spines were soft and flexible. The branchize were com- 
pletely external, being exserted through the branchial openings in the form of 
copious long filaments.
