Nono/jsis bacJici, about twenty specimens taken from deeper 

 towing in Vineyard Sound. 



Lafcea calcarata taken in surface tow near Gulf Stream. This 

 is more usually a littoral form and its presence at this distance 

 from land is not common. It is fairly common in the surface 

 tow at Woods Roll. 



Obclia were found in considerable numbers at the surface and 

 near shore. Several species were taken, two of which, 0. 

 geniculata and 0. flabcllata were most common. 



Aglawa hcmistoma, numerous specimens taken at surface near 

 the Gulf Stream. So far as I am aware this is the first record 

 of this medusa within this region. The following cut, Fig. I,

will give a good general impression of this beautiful medusa. 

 In size the specimens varied from two to four mm. in height by 

 about half that in width. It was not possible to distinguish any 

 sense organs on the specimens, the preservation in formalin hav- 

 ing apparently rendered the otocysts, if present, indistinguishable. 

 Incidentally it may be mentioned that this is a familiar effect with 

 specimens preserved in formalin of any considerable strength. 

 Even in 5 per cent, solutions it has this effect in many cases. 

 The oral end of the manubrium is reddish in color, the gonads, 

 which are borne just above the gastric pouch, are yellowish-white 

 or brownish. The peduncle of the manubrium is long and 

 gelatinous. In the specimens the tentacles had all been ap- 

 parently broken off close to the margin so that only the short 

 bases were remaining. Radial canals are eight in number and 

 extend downward upon the peduncle. 



Several specimens of an interesting Trachynemid were taken in 

 the same locality. Most of them were considerably damaged,
