ICHTHYOLOGY ACANTHOPTERYG1I. 103 



The name of Glaucosoma has been given by Schlegcl to a fish, which is 

 remarkable among the Sciaeuidse hy the smalluess of the spiuous portion of 

 the dorsal tin, and of which a figure only, by Burger, has reached Europe. 

 Pores in the inferior maxilla are not mentioned ; the spines of the dorsal fin 

 become longer posteriorly. P. 7; D. 9. 11; A. 3.9 ; gray- blue. 2 feet. 



Latilus princeps, Jenyns, Beagle. Head in front of the eyes bare, abdo- 

 minal fins exactly under the pectoral. D. 8. 20 ; A. 2. 2G. Galapagos. 



Scolo2isidcs inermis, Schlegel (1. c.). Allied to S. tteniopterus, but has larger 

 scales, and a scarcely perceptible spine on the suborbital bones. D. 10. 9 ; 

 A. 3. 6. Light red, with six dusky bands. 



SPAHID^. Sargus acenosus, De Kay, with transverse bands, a recumbent 

 spine in front of the dorsal fin ; Gincli. 1). 1.12.11; A. 3. 12. Louglsland. 



Dentex griseus, Schlegel (1. c.) 



Chrysophrys it/",-/////, Jenyns, Beagle. Only three rows of molar teeth in 

 the upper jaw ; resembles Ch. acitlattu, but has not a recumbent spine before 

 the dorsal fin. Galapagos. Ch. (tries, Schlegel. Profile much arched, five 

 rows of molars above and three below. D. 11. 13; A. 3. 11; gray green. 

 Ch. tionifrons, (id.) The profile of the head almost perpendicular. D. 12. 11 ; 

 A. 3. 10 ; red. Ch. major, (id.), D. 12. 10 ; A. 3. 8 ; red. 



ScoMBKiDjE. Cyljium flaco-lriiiiiieian, Smith, 111. 17- Five false fins above 

 and four below. 21 inch. 



Lichia Carolina, De Kay. The depth in proportion to the length is as 1 to 

 2 ; the first ray of the second dorsal fin, and of the anal fin, very long ; 1 foot. 

 I). 1. 6. 25 ; A. 2. 20. Coasts of Carolina. 



Paropsis is a new genus instituted by Jeuyus, which differs from Lie/tin 

 only in the complete absence of the abdominal fins. The name has been long 

 appropriated among the Coleoptera. The only species, P. signata, comes 

 from the north coast of Patagonia ; the Berlin Zoological Museum possesses 

 a specimen from Brazil. 



De Kay forms, from Coryph&na perciformis, ~Miic\\\}\.(Ti-ac/iiiioti(S(i>yciiteus, 

 Storer), a new genus, Palinurus. The spines in front of the dorsal fin are 

 not free, but connected at the base by a membrane ; a spine in front of the 

 anal fin ; operculum and prseoperculum serrated. The name is appropriated 

 among the Crabs, as the author himself remarks ; why has he not invented 

 another? The serrated operculum appears to remove this fish from the 

 family of the Scombridse ; the whole habit, however, would readily induce us 

 to recognize it as belonging to it. 



Caranx (Trachurus) declivis, Jenyns, Beagle. The lateral lines in the 

 whole length, furnished with 82 elevated plates. D. 8. 1. 35 ; A. 2. 1. 30. 

 About 8 inch. New Holland. C. tofvus (id.) Lateral line covered ante- 

 riorly with small unarmed scales, posteriorly with 36 plates. D. 8. 1. 26 ; 

 A. 2. 1. 22. Tahiti.
