Numerous (probably 500) specimens taken by Dr. Gilbert in a small lake at Koggiung. Two 

 specimens 2.26 and 1 75 inches long taken along with young salmon in sloughs or little pools of quiel 

 water along edge of Karluk River near its source, by Mi Flutter in L903. These specimens differ 

 from current descriptions, therefore, in having an increased number of spines, and the ventral spi 

 somewhat shorter. 



The following is a description of the larger specimen, 2.26 inches long 



Head 1 inbody; depth 5; eye 3.75 in head snout 3.75; maxillary 4; mandible 4; Interorbital 4.6;

 Mountain Lake, near Wards Cove. 



The specimens from Karluk Lake were obtained by Mr. Putter from a large school seen in the 

 river near its connection with a side lake and from sloughs or pools of quiet water along the river near 

 its source. These range in length from 2 to 4 inches. The largest of these last specimens have the lateral 

 plates scarcely evident : the smaller specimens show no plates at all. Examples taken at Lake McDonald 

 August 24 were full of nearly ripe eggs, as were also those taken at Kilisut Harbor July 1.
