on Ei-Tiinodorms from Puget Sound: Observations made on the Echinoderms 

 (.•ollectcd by the parties from Cohimbia University, in Puget Sound in 1896 and 

 1897. Eight sjjecies of starfishes are listed, of wliich three, PttrasUr muJtispinus, 

 Retasier gracilis, and Crihreila spiculifera, are new; and two new varieties of Cri- 

 hreJla Ixxyiuscula are characterized : C. Iseviuscula crassa and O. Ueviuscula attenuata. 

 There is reason to beheve that Echinaster tenuispinus was not from Puget Sound. 

 T am informed that specimens from the West Indies became mixed with the original 

 Puget Sound collection before it was sent to Doctor Clark. 



Up to 1905 the fauna of the deep water ofT the west coast of North America 

 was practically unknown, for only one species had been described (Archaster daw- 

 soni, by Verrill, 1880), although a wealth of material had been accumulating in the 

 U. S. National Museum since 1888, as a result of the numerous cmises of the U. S. 

 Fisheries steamer Albatross. 



In the Bulletin of the Bureau of Fisheries for 1904, volume 24, June 10, 1905, 

 W. K. Fisher described one new genus, two new subgenera, and twenty-four new 

 species based upon collections made by the Alhatross in Alaskan waters during the 

 summer of 1903 and off tlie coast of southern and central CaHfomia in 1904, as 

 follows: 



Eremicaster, new subgenus. 

 PorceUanaster {Eremicaster) 



hrarius. 

 Batliybiaster pectinatus. 

 Dipsacaster eximius. 

 Persephonaster penidUatus. 

 Benthopecten acantkonotus. 

 Dytaster gilberti. 

 Mimaster swifli. 

 Odontaster crassus. 

 PseudarchaMer ahscensis. 

 Pseudarchaster pusillns. 

 Tosia leptocerama. 

 Mediaster tenelhis.

Ilippasteria heathi. 

 Hippasteria califomica. 

 Cryptopeltaster, new genus. 

 Cryptopeltaster lepidonotus. 

 Lophaster furdUiger. 

 Peribolaster hiserialis. 

 Pter aster jordani. 

 Hymenaster quadrispinosus. 

 Zoroaster opMurvs. 

 Myxoderma, new subgenus. 

 Zoroaster (Myxoderma) sacculatus. 

 Zoroaster (Myxoderma) evermanni. 

 Brisinga exilis. 



FreyeUa fecunda. 



Although not directly concerned with the region under consideration, the 

 report by 11. Ludwig on the Asteroidea collected off the Galapagos Islands, Mexico, 

 Central and South America, by the Albatross in 1891, is of importance because 

 some of his new species occur as far north as Alaska (as, for instance, Porcelh-naster 

 pacijicus, P. waltJiarii {= Eremicaster Un^brarius Fisher) and Plutonaster abyssicola 

 ( = Psilaster pectimtus Fisher). Others are very closely related to forms described 

 in the following report. Ludwig's paper appeared July 17, 1905, as volume 32 of 

 the Memoirs of the Museum of Comparative Zoology. 



In the Zoologischer Anzciger for June 19, 1906, W. K. Fisher described Astro- 

 pecten califomicus and Alexandraster injlatus (=Poraniopsis injlata) from Monterey 

 Bay; and in New Starfishes from the Pacific Coast of North America," one new 



a Proc \Va.-hington Acad. Sci., vol. 8, 1906, pp. 111-139.
