Six species included in the above list reach Puget Sound, and five 

 extend to Tomales Bay and San Francisco. The species now consid- 

 ered peculiar are chiefly Holothurians and probably many of them 

 will hereafter be found farther south, while others may prove identi- 

 cal with the arctic species of the North Atlantic,

* Under the generic name, Leptosynnpta, I propose to separate from the typical spe- 

 cies of Synapta {S. mammillosa Esch.), such species as S. tenuis Ayres of New England, 

 and S. inliarens of Europe. These are distinguished by their more slender form, the 

 absence of prominent verrucae, fewer (12), shorter and more digitate tentacles, etc. L. 

 tenuis may be regarded as the type. Eschscholtz himself referred such species to his 

 genu's Chirodota, from the typical species of which they differ in having minute cal- 

 cireous hooks in the skin for adhesion. The typical species of Synapta have fifteen 

 tentacles, and prominent verructe.
