' Calamus leucosteus Jordan & Gilbert nom. sp. nov. " White Bone Porgy." Body 

 formed much as in Calamus penna, short and deep, with steep anterior profile and high, 

 arched back, the profile nearly straight from snout to above eyes, thence convex. 

 Head deeper than long ; the preorbital region very deep, its least depth 2J in head, half 

 greater than interorbital width. Eye rather large, 2f in head in adults; a strong 

 blunt prominence before it. Mouth rather large, the maxillary 2f in head. Outer 

 teeth in both jaws moderately enlarged, canine-like, about ten in each jaw, none of 

 them directed forwards. Highest dorsal spine 2^ in head. Pectorals very long, 2f 

 in length of body.' Ventrals 1| in head. Scales large, those on cheeks in five rows. 

 Smutty-silvery sides with vague cross bars; dorsal and anal tins with dark blotches;

 10. Scales 7-51-14. Length about a foot. Charleston, S. C. 



- Pagellus penna Cuv. & Ya\. =^Pagellus milneri Goode & Bean. For synonymy and 

 description of Calamns penna see Jordan & Gilbert, I.e. 21. 



3 According to Dr. Beau, the tyjjes of Spams chrysops and Sjyarus argyrops Linnaeus 

 are both the common scup. The large or Southern scup, if really a distinct species 

 or variety, should stand as Stenotomus aculeatus Cuv. & Val. 



* Diplodus unimaculatus {Bloch). Salema; Bream. 



This sjiecies has the teeth emarginate, as in D. rhomVoides, and it likewise belongs 

 to the subgenus Lagodon. It is distinguished from D. rhomhoides by its deeper body, 

 and by the longer second anal spine, which extends beyond the tip of the third spine 

 when depressed. It has, further, 13 dorsal spines instead of 12, and its coloration is 

 deeper and more golden. West Indies, north to Pensacola.
