REPORT ON ACTIXIARIA.

Haddon ('89) has suggested the possible identity of this form 

 with Gephyra dohrnii. Undoubtedly there is considerable 

 external similarity between the two forms, but until a more 

 thorough anatomical description is given of Gephyra their 

 identity must be left an open question. Haddon states that 

 anatomically Gephyra " belongs to the series of typical Sagar- 

 tians." and from this statement, as well as from the fact that in 

 all the specimens he examined the tentacles were arranged 

 on a typically hexamerous plan, I should be inclined to doubt 

 its identity with S. s-pongicola, which can hardly be called a 

 '•typical sagartian." Von Koch's description ('78) of the 

 anatomy of Gephyra is too incomplete to throw any light upon 

 the subject. 



Sub-family PHELLIX.F. 



7. ACTINAUGE LONGICORNIS Vcrrill. 1883. 



Station No. 64. American Shoal light bearing N. by W. 

 about 8 miles; about 40 fathoms; 1 specimen. 



The single specimen which I refer to this species I was 

 unwilling to injure, but I was able to compare it with a speci- 

 men from the United States Fish Commission and can state 

 that so far as their external appearance was concerned the 

 two specimens were practically identical. It is probable that 

 the specimen belongs to Verrill's variety carilura, though it 

 seems questionable if there be good grounds for recognizing 

 this as a distinct variety. 



Sub-order STICHODACTYLINjE. 



Family DISCOSOMIOE. 



8. DlSCOSOMA ANEMONE [Ellis) Duck.

I have nothing to add to the description of this form which 

 I have already published ('89).
