U.S.N.M. 646. Rio Brazos, Tex. G. Wurdemann. Cotypes of Gobius 
lyricus. The bottle contains seven specimens. The largest one, 77 millimeters 
total length, is a male of the present species. The other 6 specimens are examples of 
Gobionellus boleosoma (Jordan and Gilbert), 2 females 34 and 41, and 4 males 47 to 
52 millimeters total length. Girard, therefore, confused the two species, probably 
assuming the smaller species to be the young of the larger one; and it becomes neces- 
sary to decide to which one of the two species his name is to be applied. Girard’s 
figure is inaccurate and is not characteristic of either species, although it is reasonable 
to assume that he figured the largest specimen ; while the inadequate description may 
apply to both species. In order to fix definitely the status of the name lyricus, the 
largest specimen is hereby designated as the lectotype. 
U.S.N.M. 34456. Trinidad, West Indies. T. N. Gill. A single specimen, 
type of Evorthodus breviceps, in bad condition. It is without doubt a female of the 
present species. Most of the teeth are gone, but those which remain are distinctly 
bifid and due to the shrinkage of the soft parts appear longer than in normal specimens 
and rather hairlike. 
U.S.N.M. 87656. Norfolk, Ya. Creek and marshes at James Fishery. 
W. C. Schroeder. Type of Mugilostoma gobio. This is a male 27 millimeters total 
length, not in very good condition. The soft parts around the mouth are shriveled, 
causing the teeth to stand out prominently and to appear abnormally long as a single 
row of ciliform teeth. Because of the shriveling the lower jaw also is abnormally thin 
and angular and this together with ciliform teeth suggests a mulletlike mouth. In 
color, pattern and other specific characters, it agrees closely with specimens of similar 
size of the species under discussion. When directly compared with well-preserved 
specimens the type appears more slender and the ventral fin is placed distinctly in 
front of the pectoral base instead of under it, but these differences may well be ascribed 
to its poor state of preservation — the body being evidently shrunken and the wall 
of the belly collapsed. Most of the teeth are entire, but when examined with a strong 
lens a few are already seen to be bifid. 
Besides the above-described types, other specimens examined were: U.S.N.M. 
81823, Cr. Mindi, Canal Zone, January 14, 1911, Meek and Hildebrand, 2 males, 
41 and 42 millimeters; U.S.N.M. 78181, Gordo Paint, Nicaragua, March 7, 1917, 
C. G. Holland, 1 female 74 millimeters; U.S.N.M. 78136, Jamaica, C. B. Wilson, 
16 males, 32 to 51 millimeters; U. S. N. M. 88331, Porto Rico, W. C. Earle, 2 males 
31.5 and 72.5 millimeters; U.S.N.M. 88301 and 88323, Barranquilla, Colombia, 
from marshes having connection with Magdalena River, Dr. H. Hanson, February 
27, 1924. The label in the last bottle has the name “volador” written on, this 
apparently being the common name of the fish. 
The types of Gobius garmani and Smaragdus costalesi which are located in the 
Museum of Comparative Zoology, have been kindly compared by W. C. Schroeder 
with material from Louisiana, and he finds that the former are females and the latter 
is the male of the present species. The teeth of garmani are notched and in a single 
row, while that of costalesi are entire and the lower jaw has an inner row of enlarged 
teeth. The coloration and the proportion of the various parts agree closely with the 
Louisiana material. 
As to Gobius parvus Meek, the description does not include an account of the 
structure of the teeth, and is in general quite inadequate. The figure, however, 
unmistakably shows the characteristic color pattern of the present species, especially
