262 THE GENERA OF FISHES, PART II 



Ptychocheilus Agassiz, 227; logotype Ptychocheilus gracilis Ag. = Cyprinus 



OREGONENSIS Rich. 



Mylocheilus Agassiz, 229; haplotype Mylocheilus lateralis Ag.

Leptogunnellus Ayres, 26 ; orthotype L. gracilis Ayres. A synonym of Lumpenus. 



Anarrhichthys Ayres, I, 33 ; orthotype A. ocellatus Ayres. 



Mylopharodon Ayres, 23 ; orthotype M. robustus Ayres. 



Cebedichthys Ayres, I, 59; orthotype C. violaceus Ayres. 



Notorhynchus Ayres, I, 72 ; orthotype N. maculatus Ayres.

 Stephanus Basilewski. 



Nasus Basilewski, 234; orthotype Cyprinus nasus L. A synonym of Chon- 

 DROSTOMA Ag. 



Leptocephalus Basilewski, 234; logotype L. mongolicus Basilewski. Name pre- 

 occupied in eels ; replaced by Chanodichthys Blkr. 



Cephalus Basilewski, 235 ; orthotype C. mantschuricus Basilewski. Name pre- 

 occupied ; a synonym of Hypophthalmichthys Blkr. 



Culter Basilewski, 236; logotype C. alburnus Basilewski, as restricted by Bleeker 

 and Giinther. Under the head of Culter Basilewski mentions especially 

 (Cyprinus cultratus L.) the type of Pelecus Ag., although he does not 

 exactly specify this as type. He then proceeds to describe certain Chinese 

 species. For some of these the name Culter has been kept, although 

 Basilewski plainly intended to make his type Cyprinus cultratus, in which 

 case Culter would be a synonym of Pelecus. At present we follow the 

 authority of Bleeker and Giinther. 



Eperlanus Basilewsky, 242; orthotype E. chinensis Basilewsky = Salanx hyalo- 

 cranius Abbott. Name preoccupied ; a synonym of Salanx Cuv. 



Osteoglossum Basilewski, X, 244; logotype O. prionostoma Basilewski. Name 

 preoccupied by Osteoglossum Vandelli. A synonym of Ch^etomus McCl. 



Apterigia Basilewski, 247 ; logotype A. saccogularis Basilewski. A synonym of 

 Monopterus Lac. or Fluta B1. & Schn.

 Giovanni Giuseppe Bianconi (1809-1878). 

 Megalepis Bianconi, 270; orthotype M. alessandrai Bianconi (= Upenoides vit- 

 TATUS, fide Giinther). A synonym of Upenoides Blkr.

 plectognathes gymnodontes (Diodons et Tetrodons). Rev. Mag. Zool., VIII. 



Gabriel Bibron. 

 This is an important piece of work, but left incomplete at the death of 

 its author, hence becoming in some degree a stumbling block in taxonomy. It 

 was ably continued with the same material by HoUard in 1857. Edited by 

 Auguste Henri Dumeril. 

 Promecocophalus Bibron, 279 ; orthotype Tetraodon l^vigatus L. A synonym 

 of Lagocephalus Sw.
