The second anal spine is as long as the third, but stronger, its length 

 being exactly one-third of that of the anal base. 



The pectoral is not quite perfect, but its longest ray (fourth), if laid 

 straight back, would reach the vertical through the second anal spine 

 at present. 



The greatest height of the body is four-ninths of the length to caudal 

 base. The length of the head is contained 3^ times in the total with- 

 out caudal. The eye is three-elevenths as long as the head and the 

 orbit about one third as long. The length of the anal base is one fourth 

 of the total without caudal. 



The incisors are very narroic, and much compressed, the widest one 

 in the upper jaw beingonly about three-fourths of a millimeter in width, 

 while its exijosed length is scarcely 2'""'. The molars are in two rows, 

 the inner row containing larger teeth than the outer; but even the inner 

 molars are comparatively small. 



The species is our present Steiiotomus chrysops. 



Sparus argyrops, L. 



LiNXE, Syst. Nat., ed. sii, 471. 



No. 7, Garden. Porgee. 



The type is named in Linue's ow^n handwriting. It measures 183""" 

 to caudal base, and has the following characters : 



D. XII, 12 ; A. Ill, 11 ; scales 6 or 7-49-14. 



The third dorsal spine is broken, but the fourth seems almost perfect. 

 Its length is contained 3J times iu that of the dorsal base. The seventh 

 and eighth spines are only one-fourth as long as the dorsal base. 



The second anal spine is a little more than one-third as long as the 

 anal base; the third anal spine is imperfect. 



The pectoral rays are all broken, but the portion of the longest one 

 now remaining would reach to the vertical through the anal origin. 



The greatest height of the body is contained 2i times in the length to 

 caudal base; the length of the head about 3^ times. The eye is three- 

 elevenths as long as the head. The anal base is one-fourth as long as 

 the total without caudal. 



The incisors are exactly the same as in the type of S. chrysops, and 

 the molars jvist as iu the other. The eyes of the two types, as far as we 

 can see now, are both yellow. The upper jaw in both is about one-third 

 as long as the head. 



There is no apparent difference between the types of Sparus chrysops 

 and 8. argyrops; the only evident foundation for the two names is the 

 mistake as to the number of spines in chrysops and of anal rays in 

 argyrops.

The length of the specimen to the end of the large scales is about 

 195'""^, the height 95"", and the head about 62""".
