of some Salmans. It is perfectly evident that in its present stage 

 of development it does not find close relations with any species at 

 present distinguished. Should further collections of other similar 

 specimens of similar characters justify specific distinctness I 

 would propose for the species the name of 5". tetranema. 



A somewhat rare Scyphomedusa for this region was taken near

the Gulf Stream in the locality indicated in the introductory para- 

 graph, namely, Pelagia cyanella. So far as I know the only pre- 

 vious record was of a single specimen taken by the " Fish Hawk ' 

 in 1899 in essentially the same region. 



The specimen measured about 30 mm. in diameter, being im- 

 mature, as no marked development of gonads had yet occurred. 

 The previous specimen measured about 50 mm. in diameter and 

 was loaded with well-developed ova apparently ready to be dis- 

 charged. This is one of the few distinctly pelagic medusae of 

 this class which occasionally come within the limits of the region, 

 and is at the same time one of the most beautiful, rivalling Dacty- 

 loinetra, if not surpassing it in the richness and delicacy of its 

 coloring and grace of form. A fuller description of the medusa 

 will be given in a later contribution. 



In this connection may be described an interesting medusa 

 taken in the tow in Great Harbor, Woods Holl, on the evening 

 of August 1 6. Its general form is well illustrated in Fig. 6. 

 The following brief characters may further differentiate it : Bell 

 subrectangular in profile with a slight apical projection, bell 

 walls rather thin and very transparent, capable of great contrac- 

 tion in both directions ; radial canals four, rather wide and simple ; 

 manubrium sessile, with broad base and tapering to a terminal
