The type of this species, an adult male, was taken at Santa Barbara, 

 Cal., February 8, 1880, by A. Larco, an Italian fishermen. It is nuiu- 



hered in the collection of the United States National Museum. Mr. 



Larco states that this species is not uncommon about Santa Barbara in 

 spring and summer. 



This species is probably related to Plafyrhlna sinensis, but it has little 

 affinity with Platyrliina exasperata, already described by us, from San 

 Diego. In color, form of tail, and character of the dermal covering it 

 resembles the Rhinohatidce, and its affinities with /Si/rrJiina, of the latter 

 " family," are evident. 



OESCBIPTIOIV OF A NEW SPECBES OF "ROCK COD" (SEBASTICH-

By DAVID S. JOKDAN and CBIABI.ES H. OILBEKT. 



Body rather robust, heavy forwards, compressed behind, the caudal 

 peduncle short and rather slender. Head large. Mouth large, rather 

 oblique, the maxillary reaching to opposite the middle of the eye; the 

 l)remaxillary anteriorly on the level of the orbit; jaws about equal, in 

 the closed mouth; teeth, as usual, in villiform bands on the jaws, vomer, 

 and palatines. 



Top of head with the spinous ridges very thick and strong, their tips 

 bluntish, turned upward and outward; the spines on each side placed 

 nearly in a right line, so that the edge of the crown seems somewhat 

 regularly serrated. 



The following j)airs of spines are present: nasal, preocular, supraoc- 

 ular, tympanic, occipital, and nuchal. The coronal spines (found in 

 jS. anriculatns and S. ruber) are wanting in this species, as are the i)ost- 

 ocular spines (usually present in jS. xnnriiger). Interorbital space be- 

 tween the spines narrow, flat, and coarsely scaled (the elevated ridges 

 found in S. nigrocinctus being wanting). The tympanic spines are
