We have not had the material for a full study of this species, and we 

 have relied chiefly on the accounts of it given by Dr. Steindachner, in 

 the arrangement of its synonymy. Our diagnosis is drawn from the 

 figure of " Serranus fuscus'''' given by Steindachner in his Ichthyologische 

 Berichte. The names undulosus, fuscus, emarginatus, tinca,aLiid macro- 

 genis are considered by Steindachner to be synonymous with acutirosiris. 

 We have ventured with a little doubt to add chalinius of Cope; The 

 type of this species, examined by us, is very immature, only four inches 

 in length. It has the coloration of M. scirenga, the caudal truncate, 

 about 90 scales in the lateral line, a salient angle to the preopercle, 

 and the anal rays III, 10. There is little doubt that it is this species 

 rather than M. honaci. 



Dr. Bean informs us that specimens of this species in the British 

 Museum have about twice as many gill-rakers (30 on lower part of 

 anterior arch), as are found in any of the other species of Mycteroperca 

 which we have examined. 



Since the above was written we have received from our friend Dr. H. 

 E. Sauvage, of the Museum d'Histoire Naturelle at Paris, the follow- 

 ing account of the original types of Serranus acutirosiris and Serranus 

 undulosus, which tends to confirm the identification of these species 

 made by Dr. Steindachner.
