 specimens 2.26 and 1.75 inches long taken along with young salmon in sloughs or little pools of quiet 

 water along ed^ of Karluk River near its source, by Mr. Rutter in 1903. These specimens differ 

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

 somewhat shorter. 



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



Head 4 in body; depth 6; eye 3.75 in head; snout 3.75; maxillary 4; mandible 4; interorbital 4.G; 

 dorsal x-i, 9; anal i, 9.

Numerous specimens from the following localities: Admiralty Head and Kilisut Harbor near Port 

 Townsend; Shawnigan Lake, Vancouver Island; Alert Bay; Mink Arm, Boca de Quadra; Loring 

 (from both salt and fresh water); Lake McDonald and Yes Bay: Kasaan Bay; .\nkau River: Karluk 

 Lake and connecting streams and sloughs: Alitak Lake, Kodiak Island: St. Paul Island. Pribilof Group; 

 Sitka; and Pablof Falls. 



The species had been previously recorded by Turner (1886) from Sannak Island. By Bean (1882) 

 from Sitka; Port Mulgrave, Yakulat Bay; Refuge Cove and Chugachik Bay, Cook Inlet; St. Paul, 

 Kodiak Island; Sanborn Harlior, I'nga Island: Humboldt Harbor and Little Koniushi Lsland. Shu- 

 magins; Iliuliuk, L'nalaska; Amchitka: Kyska Harbor and St. Paul Island. Lakes of Kodiak Island 

 and Karluk estuary (Rutter 1899). Grantley Harlior (Scofield 1899). As Gasterosteus microcephalus 

 (Bean 1884) from Piseco Lake, Sitka; St. Paid, Kodiak; Chirikof Island; Hiuliuk Lake, Unalaska, and 

 Mountaui Lake, near Wards Cove. 



The specimens from Karluk Lake were obtained by Mr. Rutter 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.
