98 PROCEEDINGS OF THE ACADEMY OP 



May 7 th. 



Mr. Lea, President, in the Chair. 



Thirty-one members present. 

 Papers were presented for publication, entitled : 

 " On the Haploidonotinas," by Theo. Gill. 

 " On the Genus Anisotrcmus," by Theo. Gill. 

 And were referred to committees. 



The report of Mr. E. Durand upon the collection of plants recently received 

 from Dr. Lincecum, of Long-Point, Texas, in which he congratulates the 

 Academy upon having acquired in Dr. Lincecum a zealous and useful corres- 

 pondent, was read. The collection ahove referred to, of Texas plants, consists 

 of 682 species or varieties, 540 of which are Exogenous, divided as follows : 

 Polypetalous, 207; Monop< talous, 244; Apetalous, 84: Gymnospermous, 5. One 

 hundred and forty are Endogenous, of which 106 helong to Cyperacece and 

 Graminece. One Equisetum and one Fern. 



Prof. Gill exhibited and described two new species of marine fishes. The type 

 specimens of both are preserved in the Museum of the Academy, and said to 

 have been obtained at Newport, Rhode Island. 



The first is nearly related to the genera Epinephelus and Hypoplectrus. It 

 differs from the former by the nudity of the superior surface of the head, the 

 scales of the ante-dorsal region extending in front only to a semi-circular line 

 whose convexity reaches little beyond the vertical of the ascending margin of 

 the preoperculum. From Hypoplectrus Gill,* of which the Plectropoma puella 

 Cuv. et Tal. may be considered as typical, it differs by the inferior armature 

 of the preoperculum, which is similar to thatof Epinephelus. The Sen-anus scriba 

 has, also, the upper surface of the head naked, but its form is different ; what 

 generic name is to be accepted for that species is perhaps doubtful. 



The .new species may be called 



Hyporthodus flavicauda. 



The cheeks and opercula, as well as the supramaxillary bones, are covered 

 with scales. The lower jaw is naked. 



The preoperculum has at its angle a strong spine, which is itself more or less 

 dentated ; its ascending margin is vertical and quite strongly serrated ; its 

 horizontal inferior margin has also several more distant teeth. The operculum 

 is armed with three spines. 



The number of rays is indicated in the following formula : 



D. XL 14. A. III. 10. P. 17. V. I. 5. 



The color of the body may be described as tawny, minutely punctulated with 

 brown or black, which so prevail on the caudal peduncle, the dorsal, anal and 

 ventral fins, that those parts are quite black. There are on each side four narrow 

 lighter bands, along each of which are also about three light blue spots. The 

 caudal and pectoral fins are yellowish. The articulated portions of the dorsal 

 and anal exterior to a line continuous with the margin of the spinous portions 

 are lighter, and also assume a yellowish hue. The first transverse line extends 

 from the fifth or sixth spines of the dorsal to the axilla of the pectoral fin ; the 

 second from the eighth dorsal spine ; the third from the eleventh ; the fourth 

 from about the fifth articulated ray. 



The species, on account of its coloration, resembles the Hypoplectrus 

 chlorurus Gill, {Plectropoma chlorurum Cuv. et Val.,) as much as any other, but is 



* The genus Hypoplectrus is proposed for the Plectropoma puella and allied species of 

 the Caribbean sea.
