We translate from the letter of Dr. Sauvage : 



"The type of Serranus acutirostris C. V. which is now before me comes 

 from Brazil, by Delalande. It is m. 0.3G0 in length. 



"D. XI, IG; A. Ill, 11. L. lat. 95. 



" Height of the body contained 4 times ; length of head 3i in the total 

 length. Caudal scarcely emarginate. Third anal spine longer and a 

 little stronger than second. Lower jaw longer than upper; maxillary 

 reaching to opposite posterior margin of eye. Muzzle 1| times length 

 of eye, the diameter of which is 5§ times in the length of the head. 

 Preopercle finely denticulate, the teeth at the angle stronger. Color 

 uniform reddish brown." 



A drawing accompanying this shows the ma^zillary to be half the 

 length of the head, and the angle of the preopercle somewhat salient. 



" Serranus undulaeiis is so near to the other species that, except for 

 the presence of undulating lines, I cannot distinguish the two. The 

 caudal is, however, a little more convex." 



This specimen is doubtless the young of the one called acutirostris. 



Professor Doderleiu, in his recent "liivista del genere Upinephelus,''^ 

 calls attention to the i)robable identity of Sparus scirenga with Serra- 

 nus acutirostris. Bafinesque's description is of little value, but he says 

 that his species is the fish called " Scirenga^^ at Palermo. According to 

 Doderlein, the ^^Scirenga^^ of the Palermo market is the M. acutirostris. 

 There seems, then, to be no doubt as to the species which Rafinesque 

 had in mind. It appears therefore necessary to substitute scirenga for 

 acutirostris.
