Cypeinidju. 
Jordan (e) gives an identification of the species of Cyprinidce and 
Catostomidce described by Girard in the P. Ac. Philad. 1856. This use¬ 
ful work contains positive identifications of very many of his types not 
hitherto recognized, accompanied by a number of synonymic notes too 
numerous to be recorded. A few of these notes are taken from manu¬ 
scripts of Meek, who has examined the series of Girard’s types in the 
Academy of Philadelphia : pp. 118-127. 
Ictiobus velifer , Raf. : notes by Jordan & Meek, (a) pp. 2 & 16 ; the 
authors have as yet been able to distinguish 3 species only as belonging 
to the group Carpiodes, viz., I. velifer , Raf., cyprinus , Le S., and carpio ; 
it still remains a matter of doubt ‘whether 2. timidus, damalis , grayi , 
thomsoni , bison, selene, cutisanserinus , and difformis are really distinct 
species, or merely varieties of one polymorphous species, velifer. I. buba- 
lis and carpio , Raf. : on these and allied species ; iid. t. c. p. 13.

Pimephales. Blatchley (b) is of opinion that Hyborhynclius is un¬ 
worthy of retention, and that there are only 2 species, P. promelas and 
notatus, and of these the synonymy and notes are given, p. 63. P. prome¬ 
las, Raf.: notes on this species, the young of which is identified as Coliscus 
parietalis , Cope ; Jordan & Meek, (a) pp. 3 & 9.
