80. ORTHOPRISTIS POEYI. 



Orihoprifitis jwci/i (Sciultler MSS.) Pooy, Synoysis, 18G8, ol'2 (Havaua). 



Habitat: West Indies. 



Etyuioloiiy: Named for Prof. Folii)e Poey. 



Of this species we have exainiiied several speeimens, all from Ha- 

 vana. The species is very close to OrthopHstis chrysopterus, but the 

 body is more slender and the scales are rather longer. 



81. ORTHOPRISTIS CANTHARINUS. 



rrixiipomu cantlKxrhutm Jonyus, Voyaj:;e Beagle, Fish.. 10, 1812 ((Jalajiagos Islands). 

 Uamulon modcstttm Tscbmli, Fauna Peruana, 11, 1844 (Peru). 



Habitat: Pacific coast of tropical America. 



Etymology: From Ganthanis { = kSjwndyliosoma), a genus of sparoid 

 fishes, which this remotely resembles. 



This species is known to us from two examples, each about a foot 

 long (164:8, M. C. Z.), from the Galapagos Islands. Another, supposed 

 to be of the same species, is in the U. S. National ^Museum from Guaymas. 

 The scanty description of Jlfcmidon modcfituin Tschudi, a species said to 

 be rare along the coast of Peru, agrees in all respects so far as it g:oes 

 and is i^robably the same species. It could not be Orthopristis chaJccns, 

 Orthopristis brevipinnis, or Isacia conceptionis, as these species have the 

 second anal spine quite small. 



82. ORTHOPRISTIS LETHOPRISTIS. 



Orthopristis hthopristis Jorilau A: Feslcr, Proc. Ac. Nat. Sci. Phila. 1880, 36 (Gala- 

 pagos Islands). 



Habitat: Galapagos Archipelago. 



Etymology: /.rjOo'mi, to forget; -f>t<TTcc, used for -fiiffrr^i;, a saw; a ref- 

 eience to the entire preopercle. 



This si^ecies is known from the original type (2G;)4:7, M. C. Z.), 15 

 inches long, from the Galapagos Islands. 



83. ORTHOPRISTIS BREVIPINNIS. 



rristipoiiDi lirtripinnc Stoiudacliner, Iclilh. Nofcizen, viii, 1860, 10 (Mazatlan). 



Habitat: I'acific coast of tropical America. 



Etymology: Brer is, short; piniio, lin. 



This species and the preceding form a transition from Microlrpidotus 

 to typical (>rtlto2)ristis. From their resemblance to Jsavia conciptionis, 

 we have suggested for them the subgeneric name of Isaciella.
