This species is nearly colorless : the tentacles and manubrium are of a very 

 faint bluish tinge, and the gonads are opaque milky white. 



Several specimens, Male atoll, near Male island, December 26, surface. 



This species is most closely allied to Eutiineta gentiana Haeckel, from the 

 Canaries, but differs from it in the form of the bell, and in having much smaller 

 marginal cirri. The gonads are more prominent, but occupy a shorter portion 

 of the peduncle. In the form of the bell it resembles Eutimeta levuka Agassiz 

 and Mayer, but the peripheral position of the gonads in the latter is an im- 

 portant point of difference. 



Eirene danduensis, sp. nov. 



Plate 1, Fig. 5. Plate 3, Fig. 6. 



The bell is flatter than a hemisphere, somewhat conical in outline, with 

 rather thin gelatinous substance : it is twenty-five mm. in diameter and about 

 one third as high. There are thirty-two tentacles, of which the four opposite 

 the radial canals are at least one fourth longer than the others. Each tentacle 

 bears two lateral cirri at its base, and there are also about seventy small pa- 

 pillae scattered irregularly along the bell margin. There are thirty-two oto- 

 cysts, eight to each quadrant, and each contains about five spherical otoliths. 

 The peduncle, the most distinctive feature of this form, is long for the genus, 

 reaching well below the bell opening, and is conical in outline. The proboscis 

 is about one half as long as the peduncle. It may be extended to nearly double 

 this length, but cannot be retracted within the bell opening. The mouth bears 

 four simple lips. 



The spindle-shaped gonads occupy the distal two thirds of the radial canals. 

 The bell is colorless. The gonads are bluish green. 



A single specimen was taken on January S, off the east face of Haddummati 

 atoll, in an open net, at two hundred fathoms. 



This Medusa is distinguished from all described species of Eirene by the very 

 considerable length of the peduncle and proboscis. 



Timoides agassizii, gen. et sp. nov. 



Plate 3, Figs. 10, 11. 



Timoides forms a new genus of Eucopidae, belonging to that division of the 

 family characterized by j^ossessing numerous otocysts and tentacles, and nu- 

 mei'ous cirri on the bell margin. The gonads are borne on the radial canals, 

 but are wholly restricted to the peduncle, which is very long. The lips are 

 large and form an important feature. By far the most characteristic feature 

 of this genus, which in the main resembles Tima, is the presence, between the 

 radial canals, of blind centripetal canals arising from the ring canal. 



The Medusa is bell-shaped, of much the same outline as Tima formosa Agassiz. 

 The gelatinous substance of the bell is very thick. The extreme diameter is
