NO. 3 TELEOSTEAN FISHES — GOSLINE 35 



usually do. In relation to this structural difference the supraorbital- 

 antorbital and lacrimal pumping mechanisms so typical of the Clupei 

 are never present in Osteoglossi, in which the area usually occupied 

 by these bones is filled by a varied series of bones rather difficult to 

 interpret. Certainly some members of the Clupei have also lost their 

 nasal diverticula, e.g., Esox and Umbra, but in these the bones of the 

 snout region have never progressed so divergently as in the 

 Osteoglossi. 



In the same paper (Gosline, i960) the elopids and albulids were 

 placed together in the suborder Elopoidei of the division Clupei. The 

 presence of sensory canals in the premaxillaries of albulids, unique 

 among recent teleosts, points up once again the divergence between 

 these two groups. 



Bathyclupeiformes. — It has been adequately demonstrated by others 

 that the single contained family belongs in the Perci formes. 



Galaxii formes. — Berg erected this order for the genera Galaxias 

 and Neochanna. Gosline (i960) has followed the more usual taxo- 

 nomic procedure of grouping these genera with Prototroctes, Lovet- 

 tia, Aplochiton, and Retropinna (and of placing the whole assemblage 

 in the Clupei formes). The possibility that Berg is correct in removing 

 Galaxias and Neochanna from the other genera mentioned probably 

 deserves further attention. 



Scopeliformes. — The presence of fulcral scales and of well-de- 

 veloped temporal fossae in the rear of the skull of the basal iniomous 

 genus Aulopus makes it impossible to derive the Scopeliformes from 

 anything higher in the scale of modern teleosts than the elopoid 

 Clupeiformes. (For a discussion of the relationship between the 

 Scopeliformes and Clupeiformes, see Gosline, in press.) 



Ateleopiformes, Giganturiformes, and Saccopharyngiformes. — The 

 present author has no new information on these groups. 



Mormyriformes. — The close resemblance between the caudal skele- 

 ton of these fishes and those of the osteoglossoids (Gosline, i960) 

 bears out the interrelationship between these groups hypothesized on 

 other grounds. 



Cypriniformes. — The rather remarkable similarity between the 

 caudal skeleton of the characin B rye on and that of the round herrings 

 has been remarked upon in section I of this paper. In pelvic osteology, 

 however, Brycon appears to be more generalized than the modern 

 herrings. 



Angidlliformes. — No new information can be added here. Suffice 

 it to say that the eel jaw structure can be derived only from that of 

 the Clupeiformes among living teleosts.
