" Preliminary Report on a Collection of Medusa from the 

 Coast of British Columbia and Alaska," by Louis Mur- 

 bach am' Cresswell Shearer. Annals & Mag. Nat. Hist., 

 7th series. Vol. 9, No. ^9, pp. 71-73- Jan., 1902. 



In the summer of 1900 Cresswell Shearer, Esq., accompanied 

 by Prof. MacBride of McGill University, in a trip along- the coast 

 of British Columbia, and collected a number of species of Medusae, 

 to which additions were made by Prif Kincaid of Seattle. The list 

 of species identified include the following : 



9. Hippocrene Mertensii. 



10. Thaiimantias celliilaria. 



11. Proboscidactyla brevicirata. 



12. Phialidium lantfuidum. 



13. P. greg'arium. 



14. Mug-gisea Kochii, one of the 



SiPHONOPHORA 



1. Codonium apiculum, sp. n. 



2. Turris breviconis, sp. n 



3. Gonionemus Agassizii, sp. n. 



4. ,, vertens, sp. n. 



5. Polyorchis inuta, sp. n. 



6. Mesonema victoria, sp. n. 



7. Syndictyon angulatum. 



8. Dipurena dolichogaster. 



F"our additional species are recorded from the same coast, but 

 with some doubt as to identity owing to the imperfect mode of 

 preservation of the material examined. These include : 



a. Sarsia eximia. b. S. rosaria. 



c. Atollia Bairdii. d. Obelia polystyla. 



The descriptions of the five new species are then given. This 

 paper opens up a most interesting field of research in the inverte- 

 brate fauna of the west coast.
