Page 541. Promicrops should be reunited with Upineplielus. Our 

 species may stand as: 

 §53. E. gwasa (Pocy) J. & G. ' 



It is however probable, as suggested by Dr. Gill, that the Epine- 

 pJielus guasa is simply the very old form of U. nigritus, also known as 

 '' Guasa'''' or " Warsaw'''' by the Florida fishermen. 



Page 542. Dules auriga should be omitted, as it has probably never 

 been taken on our coast. 



Page 543. Instead of Rhypticus decoratus read:

And add to the synonymy : 



{Blijjptieiis tiir/rijx'uutis Gill, Proc. Acad. Nat. Sci. Phila. 1861,53: 1 Promicroptenis 

 decoratus Cope, Proc. Acad. Nat. Sci. Phila. 1870, ll'J.) 



This species inhabits the Pacific coast of Mexico and Central America, 

 and we doubt its occurrence on our Atlantic coast. The specimens ob- 

 tained by Professor Cope at Newport may belong to some different 

 species.* 



Page 54G. Instead of XenicJithys Gill read : 



2§1.— XENISTIUS Jordan & Gilbert (gen. nov.). 



In the typical species of XenicJithys Gill, the soft dorsal is much longer 

 than the spinous dorsal, and composed of 18 rays ; the anal is also sim- 

 ilarly elongat(^, of 10 to IS raj^s. In X. calif orniensis, tbo soft dorsal is 

 shorter than the spinous dorsal, and composed of 11 or 12 rays ; the 

 anal is also short. The latter species may be taken as the type of a 

 distinct genus, which may be called Xenistins. (ccv«c, peculiar j iffrwy, 

 sail, for dorsal fin.) 



* Professor Cope describes the specimen from Newport as follows : "D. II, 26; A. 16 ; 

 scales 11-98-46, counted from base of second dorsal spine. Dorsal lius connected by 

 membrane as elevated as that of the first dorsal. Head (i'rom premaxilla to end of 

 spine) more than 4 times in length, including caudal lin. Pectorals not narrowed. 

 Eye 5.33 times in length of head. Otherwise, as in P. maculatus Holbr. Color dark 

 brown, covered with round pale spots as large as the orl)it, each with a brown cen- 

 tral si)ot. They extend on the dorsal and jiroximal caudal tins. Second dorsal, anal, 

 and caudal fin broadly blackish-edged."
