DISTRIBUTION 



The genus Liparis is confined to the shallow cold water ot the 

 Northern and Southern Hemispheres. The majority of the known 

 species are from northern regions. Up to the present time only two 

 species are known from Antarctic regions. Many of the species are 

 found in the tide pools. At least 21 of the 30 species have been taken 

 in less than 10 fathoms. Only 5 species have been taken from depths 

 below 100 fathoms and 3 from below 200 fathoms. The greatest 

 depth at which a specimen has been taken is 250 fathoms. We may 

 provisionally place the lower margin of the bathymetric distribution 

 of the genus at about this level. 



Limits of distribution. — The tide-pool species extend farthest south 

 on the Pacific coast of America. Species of Liparis mucosus are 

 infrequently taken in the deep tide pools at Pacific Grove, Calif., or 

 just north of parallel 36° N, On the Asiatic coast specimens of 

 Liparis agassizii have been taken at Mizako, north of parallel 39° N.^° 

 The species is not a typical tide-pool species, and the specimens 

 recorded may have all been taken with seines below the tide pools. 

 The writer did considerable collecting in Hakodate Harbor but 

 obtained no specimens of Liparis from the tide pools. The Japanese 



'D Smith and Pope (1906) record specimens of Liparis agassizii obtained from the museum at the Fishery 

 Experiment Station, Shiogama, Matsushima Bay, Japan.
