936 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY IV. 
The character of “lower jiharjngeals united” has little importance 
in this group. In Gerres plumieri, as in nearly all the species examined 
by us, the bones are not at all co-ossified, although very close together.

broid fish, and not an Embiotocoid. 
Page 590. The genus Holeonotiis Agassiz should be recognized for 
those species of Amphistickus which have the lower lip without frenum, 
and Brachyistius Gill for those of 3Iicrometrus, which have the frenum.

specimen of Tautog which had in some way lost the anal tin; this specimen seems 
to have been sent from Charleston bj' Ur. Garden to Linnseus. If Micropttrus and 
other generic names, based on abnormal or mutilated specimens, be adopted, we must 
substitute Hiatula for Tautoga.)

This group is distinguished from Harpe by the smaller scales (Lat. 1. 
45 to C5), which scarcely encroach on the bases of the soft dorsal and 
anal. In the ])resenti classification of the Lahrida’, this group may be 
recognized as a distinct genus, although differing from llarpe in no re- 
spect of importance. Species few. [rpir/oi;^ a runningj zcy-vj, oar.)

This species seems to be widely distributed, and varies considerably 
with age and sex. The following is a description of the young (“jt/ore- 
n/i.s”), supposed by us at first to belong to a difierent species: 
Olive-browui ; a greenish stripe along side of back; a dark- brown 
lateral band from gill-opening to middle of caudal, on level of eye; a
