The localities where this species was collected by ' William Scoresby ' are near the coast around the 

 eastern entrance to the Strait of Magellan. 'Discovery' only found it at the Falkland Islands. Most 

 of the specimens of this beautiful and interesting medusa are in an excellent condition. The largest 

 specimens previously observed were 22 mm. in diameter; some of the present specimens are 25 mm. 

 wide. Their size according to the seasons are as follows: 



Month Jan. Feb. April May 



Diam. (mm.) 5-25 7-25 8-18 9-12 



Specimens 58 32 35 2 



The previous records were from November to February. 



Distribution. Up to now this species has only been observed at the Falkland Islands, where it 

 was found in great abundance. As will be seen from the above records, it is also common in the 

 region of the Strait of Magellan.

 1939 Gossea brachymera Russell, p. 707. PI. i; text-figs. 1-3. 



Occurrence: St. WS 89. 7. iv. 27. 53° 01' S, 68° 07' W to 52° 59' 30" S, 68° 06' W. Net: N 7-T 23-21 m. i speci- 

 men. N 4-T 23-21 m. I specimen. 

 St. WS 833. I.ii. 32. 52° 28' S, 68° 00' W. Net: N 7-T 38-31 m. 40 specimens. 



Both localities are near the eastern entrance to the Strait of Magellan. 



Bigelow described this species from a single small specimen, 5 mm. in diameter, taken in Acapulco 

 Harbour on the Pacific coast of Mexico. A new description was given by Russell, who examined 

 17 specimens, 4-5-7-5 mm. wide, taken off Grand Island, Louisiana, in the Gulf of Mexico. From a 

 zoogeographical point of view it is very interesting that this same species also occurs oflF the southern- 

 most part of South America. The specimens collected by 'William Scoresby' are much larger than 

 any seen before, being up to 20 mm. in diameter; they also have a much larger number of tentacles, 

 but in all structural details they agree so well with the previous descriptions that there can be no doubt 

 of their identity. The following remarks are mainly occasioned by the considerable size of the speci- 

 mens. Some of them are in a very good state of preservation. 



The two specimens from St. WS 8g are 14 mm. and 16 mm. wide; the numerous specimens from 

 St. WS 833 vary between 11 mm. and 20 mm. in diameter. The general shape of the medusae agrees
