I have no knowledge of this species as being taken near Ithaca. 

 There are a few specimens in the Museum of Cornell University 

 from the Lake, but no definite locality is given. Several were 

 taken by Mr. Harris and myself from a small stream near Monte- 

 zuma.

 5 in the length of the body; individual variations many. 



8. AMIURUS VUL.GARIS * Thompson.

This species seems to be quite scarce; I found but one speci- 

 men among over one hundred of the former species. It was 

 taken near Ithaca. 



Lower jaw decidedly longer than the upper. Upper lip thin; 

 anal rays 19; caudal fin slightly emarginate. Physiognomy con- 

 siderably different from other species of the genus.
