NOTES UPOX THE DISTRIBUTION AND HABITS OF 

 SOME PUGET SOUND INVERTEBRATES.* 



By N. R. Harrington and B. B. Griffin. 



The following faunal description has been presented with a 

 view of furnishing a basis for more extended work in the future. 

 The attempt is made here to give an outline of the general char- 

 acter of the Puget sound region for the benefit of embi\vologists 

 and other investigators that may have an opportunity of visiting 

 this interesting region. Essential data are also supplied for the 

 specialists now engaged in systematic work upon the various 

 groups. Many of the scattered notes on distribution and habits 

 may interest those concerned with problems of zoogeography 

 and evolution, as illustrating how rich a field is here presented 

 for such researches. 



In the systematic work, we have mainly been guided by 

 the papers of Dall, Andrews, Whiteaves, Stimpson and Keep, and 

 the monographs of Quatrefages, Verrill, Semper, Agassiz,and the 

 various authors of the Challenger Report Expedition. For the s\'s- 

 tematics of the mollusca, we are especially indebted to Judge J. G. 

 Swan, of Port Townsend, for his gift to the expedition of his pri- 

 vate collection of west coast shells identified by P. P. Carpenter, 

 without which it would have been impossible to determine many 

 species. 



A short account of the Neah Bay fauna will be found at the 

 end of this paper. For the opportunity of extending research to 

 the extreme boundary of the northwestern Washington coast, 

 as well as for many other courtesies, we are under obligation to 

 Mr. John Libb^^ of the Puget Sound Tug Boat Company. For 

 cooperation and assistance in dredging, we are indebted to Cap- 

 tains dinger and Bolong, and, by the generosity of Captain 

 Sprague of the Sea Lion, we were enabled to make very valuable 

 littoral collections in this somewhat remote region. 



Part I. The Littoral Region. 



Ttie west coast about Puget Sound is in general precipitous and 

 in many localities the shore shelves off rapidly to a depth of from 

 five to ten fixthoras witliin a few feet of the land. In regions
