(1943b) and reports it from Iceland on the shrimp Spirontocaris 

 lilljehorgi and from east Greenland (1943b) on the shrimp Eiialus 

 gaimardi. The specimens from Point Barrow form the first record 

 from America. 



At least 10 specimens of Schizopr actus in flatus Aurivillius were 

 taken from branchial baskets of the tunicate Boltenia ovifera. Of 90 

 B. ovifera examined from 175 feet on October 14, 1949, seven con- 

 tained copepods measuring from 4.5 to 5.0 mm. in length and the 

 bodies of the hosts (greatest dimension) were from 12 to 29 mm. 

 Both larger and smaller tunicates were free of parasites. A 13-mm. 

 B. ovifera from 341 feet contained a copepod, and two 35-mm. speci- 

 mens from 453 feet each contained one. These two B. ovifera were 

 from a cluster of 26 specimens in which the holdfasts and stalks were 

 entwined. Although this copepod has been reported from Spitsbergen, 

 northern Norway, west and east Greenland (Stephensen, 1943b) and 

 Arctic Canada (Wilson, 1920), it is new to Arctic Alaska. In east 

 Greenland it usually lives in a species of Phallusia (Stephensen, 

 1943b). 



Specimens of a new species of Dorypygus were found in the 

 branchial baskets of Boltenia echinata: two females (3.5 mm. long) 

 with a large number of yellowish eggs (preserved) from 217 feet; 

 one (4.5 mm. long) from 175 feet (October 14, 1949) ; and others. 

 B. echinata is a new host and this genus of copepod is new to Alaska 

 and Arctic America. 



A large unidentified female copepod belonging to the family En- 

 terocolidae was found by Dr. Donald P. Abbott among the unopened 

 tunicates sent to him. 



A single specimen of Haemobaphes cyclopterina (Fabricius) with 

 a bright-red body 6.5 mm. long was taken from the gills of an Arctic 

 cod, Boreogadus saida, that was brought in on June 21, 1950. The 

 two cylindrical egg sacs, 6 mm. long, were white. Although this 

 copepod is a well-known Arctic, subarctic, and north temperate 

 species, it has not been reported previously from Arctic Alaska or 

 from the Arctic cod as a host. 



Order CIRRIPEDIA 

 Suborder Thoracica 



Although only three species of this group were taken, they made 

 up in number of individuals what they lacked in number of species. 

 Dr. Dora Priaulx Henry identified these barnacles.
