Family GINGLYMOSTOMID^. 



I. Ginglymostoma cirratum (Gmelin). 



A single specimen taken, 27 cm. long. The body and fins are light brown- 

 ish, marked with small black spots about as large as pupil, those iu front of dorsal 

 arranged rather uniformly in cross-series. Snout unspotted. Lower side of bead 

 whitish, unspotted. 



Family GALEID^. 



2. Mustelus lunulatus (Jordan & Gilbert). 



Plate I, Fig. 1. 



Five specimens were secui'ed seeming to agree in all respects with an indi- 

 vidual collected by Dr. Jordan from the type locality, Mazatlan. In a young male 

 53 cm. long tlie claspers do not project beyond the edge of the ventral fin ; in 

 another 64 cm. long they are fully developed, protruding beyond edge of ventral for 

 about 4 cm. A male from Mazatlan (68 cm. long) has the claspers undeveloped, 

 not reaching beyond margin of ventrals! This seems to indicate considerable irregu- 

 larity in the sexual development of the species. The young of M. lunulatus are as 

 yet unknown.
