478 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
from the above that the name chrysopterum can not properly be retained 
for this or any other species of Hamulon. The name aurolineatum 
has been applied by Jordan & Gilbert to this species, but erroneously, 
as is Shown beyond. Jordan & Swain have therefore given the species 
anew name, as none of those by which it has been called (chrysopte- 
rum, aurolineatum, caudimacula, parre) were originally intended for it. 
The name Hemulon rimator is given in allusion to the inquisitive habits 
shown by the young of this species. They swarm about the wharves 
and are a nuisance to the fishermen, nibbling off the bait. 
Both Heamulon rimator and H. plumiert have been recorded from 
‘‘New York,” but no good evidence exists that either species passes to 
the northward of Cape Hatteras. None of the others range far north 
of the Tropic of Cancer.

This little fish is very abundant at Havana, where it is often brought 
into the market. It is smaller in size than any other of the genus 
except H. chrysargyreum. It has been taken at Garden Key, Florida, 
but was not observed at Key West by Prof. Jordan. In its relations 
it is extremely close to H.rimator. It is more slender and fusiform in 
outline, and its coloration is usually of a deeper yellow, otherwise we 
are unable to point out any differences of importance. 
We have adopted the name awrolineatum for this species, and not for 
H. rimator, on the strength of the following account of the typical 
specimen of Hamulon aurolineatum received from Dr. H. E. Sauvage, 
of the museum at Paris: 
Hemulon aurolineatum, Brazil, Delalande, type. Length of the body, 0.220 m.; 
height of body, 0.055 m.; length of the head, 0.60 m. Height of the body contained 
nearly four times in the total length, and three and one-half without the caudal. 
As the description of Cuvier & Valenciennes agrees in other respects 
equally well with either species, the above measurements leave no doubt 
of the identity of their type with H. jentguano. Hamulon rimator, young 
or old, is never so slender as the above measurements would indicate. 
Specimens are in the museum at Cambridge from Havana, Rio Ja- 
neiro, Ceara, Maranhao, San Francisco, St. Thomas, and Porte Seguro. 
Among those from Cuba is Poey’s type of H. jeniguano.
