 to 52, 35 before dorsal. Interorbital space Hat, slightly greater than eye. 

 Pectoral iin extending scarcely beyond dorsal and anal; base of ventral 

 midway between eye and base of caudal, its rays reaching beyond middle 

 of base of anal; dorsal opposite anal, its anterior rays 2i in head. Pec- 

 toral with an oblique white blotch across it.s lower half, and with a narrow

Page 746. According to the studies of Mr. Putter and Dr. (iilbert all 

 the forms of Gastcrosteits should probably be reduced to a single species

 into a number of forms which diiicr in the degree of armature of the body.
