478 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



from tlio above that the iiaiiu' rhriiHopterum can not properly be retained 

 for til is or any other specii's of ]J(vmulon. Tlui name anrolinc<itum 

 has been applied by Jordan «& Gilbert to this species, but erroneously, 

 as is shown beyond. Jordan & Swain have therefore given the species 

 a new^ name, as none of those by wliicli it has been called {clirysopfc- 

 rum, ouroUneafum, candimaeula, 2>f(y>'(i') were originally intended for it. 

 The name Ilcemulon rimator is given in allusion to tlie inquisitive habits 

 sliown by the young of this si)ecies. They swarm about the wharves 

 and are a nuisance to tlie fishermen, nibbling off the bait. 



Both Ilcrmulon rimator and H. plumieri have been recorded from 

 "New York,"' but no good evidence exists that either species passes to 

 the northward of Oape Hatteras. None of the others range far north 

 of the Tropic of Cancer.

Habitat: West Indies; Florida Keys to Brazil. 



EtjTnology: Aurum^ gold; lincatus, striped. 



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 JI. chnjsargyrcnm. 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 dcei)er yellow, otherwise we 

 are unable to point out any differences of importance. 



We have adopted the name aurolineatum for this si)ecies, and not for 

 H. rimator^ on the strength of tlie following account ^^{ the typical 

 specimen of Hamnlon aurolineatum received from Ur. H. E. Sauvage, 

 of the museum at Paris : 



Hfrmvlon aurolineatum, Brazil. Debuande, typ<>. Lenjitb of the body, 0.220 m. ; 

 height of body, 0.055 ni. ; length of the liead, 0.60 m. Height of tlie 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 ty])e with J f. jeniguano. II amnion rimator, young 

 or old, is never so slender as the above measurements would indicate. 



Specimens are in the museum at Cambridge from Havana, Eio Ja- 

 neiro, GenrA, Maranhfio, San Francisco, St. Tliomas, and Porto Seguro. 

 Among those from Cuba is Poey's type of JI. jeniguano.
