? CUBOIDES, sp. 



A medusa referred to Cuboides was collected by Prof. S. I. Smith, ou 

 Oeorge's Bank, in 1872, Baclie Coll. This is the most northern limit of 

 ibis genus in the Gulf Stream region. The Albatross collected an uni- 

 dentified ? Cuboides and a % Sphenoides from the followiug locality: 



MUGGM.ZEA KOCHII? Chun. 



The genus Mu(/(/icca as limited by Dr. Chun occurs in the Gulf Stream, 

 although uot collected by the Albatross, or at least not represented in 

 the collection sent me. I have seen specimeus of this genus in the 

 neighborhood of Key West, Fla., and still others collected by a friend 

 oft* Kantucket. It also occurs at Beaufort, N. C. It closely resembles 

 the M. Kocliii of Trieste. 



PHYSOPHOK^ (PHYSOPHORID^, Auct.) 



There are several genera of Physophora),* exclusive of the Ehizo- 

 physidse and Physalia, found in the Gulf Stream. They are as follows: 



Stephanomia, M. E, (Forskalia, Koll), Atlantica, Pewkes. 

 Tortugas, Florida, Bermudas. 



Agalma OKENHjt Esch. 



Tortugas, Florida, Bermudas. 



The Agalma papillosum^ Few., is possibly the youug of this species. 



(Agalma elegans, Few.) 



The bottle in which a specimen of this species is found is labeled 

 "Gulf Stream." {Bull. Mus. Comp. Zool, vol. ix, No. 8.) It is doubtful 

 whether elegcms, which is a boreal species, ever gets far south in the 

 Gulf Stream. 



A. elegans, Few., is probably one of the "forms" described by Sars as 

 Agalmopsis elegans. The question of its generic name resolves itself 

 into whether A. OJcenii, Esch., is specifically difierentor geuerically the 

 same as A. elegans, Few. As an expression of individual opinion the 

 writer regards them as generically identical. The main differences are 



* Fragments of a member of the family of Agalmidae are found from Stations 2175, 

 2210, and 2235. The genus could not be recognized. 



t Crysiallodes rifjidmn, Hgeek, Cr:;staUomia, Dana, and Agalma brece, Hux., are re- 

 garded as syuoijyms of A. Okenii, Esch.
