scales. The Abramidine type, on the other hand, may 
be traced not only in the long anal tin and the naked- 
ness of the median dorsal line throughout a consider- 
able part of its length in front, but also in the similar 
appearance of the median ventral line, which is sharply 
carinated and naked all the way from the isthmus to 
the vent, the latter being situated, as usual, just in 
front of the anal tin. The most natural course is there- 
fore to regard the genus as the type of an offshoot 
from the common stock of the Bleaks and Breams. 
But in the structure of the mouth, the pharyngeals, and 
the scales the Zope shows signs of transition from the 
true Breams to this genus. Pelecus is further distin- 
guished by its long and pointed, almost scythe-shaped 
pectoral fins, which recur, however, in some other ge- 
nera, notably Chela, a genus belonging to Indian and 
the East Indian Archipelago, fairly rich in forms, and 
very nearly approximated to Pelecus. This latter 
genus was established by Agassiz" in 1835, and con- 
tains only one species, essentially differing from Chela 
merely in the irregular, undulating lateral line. 
Fries and Ekstrom adopted the genus — though as 
a subgenus entitled Chela — in the previous edition of 
“ Scandinavian Fishes" (1837), under the Swedish name 
of Skdr-Braxnar ; but for the species they retained the 
Linnaean name of Skarknifven (Carving-knife).
