behind the second dorsal. As in all young the eyes are larger 

 than in the adult, being contained 4 times or less in the head, 

 while the spiracles are more open and about 4 in the eye. The 

 subcaudal lobe is very slightly developed, its elongation evidently 

 being a post-embryonic development.

 The genus Squalus is typically one of cool, temperate waters 

 and is primarily distinguished by the conspicuous stout sharp 

 spine in front of both the first and the second dorsal fins, and 

 by the teeth which are alike in both jaws, with obique cusps 

 and cutting edges nearly parallel with the edge of the jaw. 



Smith and Radcliffe described a small male Squalus, 325 

 millimeters long, from the west coast of Luzon, under the name 

 of Squalus philippinus. It was dredged off Sombrero Island, 

 at a depth of 236 fathoms. 



It is therefore a matter of considerable interest to find two 

 more specimens, this time in shallow water, the species being 

 apparently not considered rare by the Dumaguete fishermen. 



My specimens are both females; they measure, respectively, 

 645 and 655 millimeters long over all. I follow Garman in 

 placing philippinus under the synonymy of S. fernandinus.
