^26 Mr. E. T. Giinther on 



to be provided with a central, clear, refrin^eut, lenticular 

 bod}^ surrounded by deeply pigmented cells (fig. 3). 



The species is named after my former tutor, Mr. Edward 

 Chapman, M.P., who, as Science Tutor and Fellow of 

 Magdalen College, has done so much to promote the 

 interests of natural science in Oxford. 



JEqiioridae. 

 Halopsis ocellata, Agassiz (?). 



Two iEquorid Medusie were taken from between 1J.70 and 

 1275 fathoms and the surface. They were without gonads, 

 but possessed a short manubrium, a well-developed velum, a 

 very muscular subumbrella, 8 radial canals, and about 60 

 and 42 tentacles respectively. The diameter of each was 

 6 millim. Owing to the imperfect preservation of the 

 specimens, it is difficult to refer them to their proper position 

 with any degree of certainty, although they would seem, if 

 mature individuals, to belong to the genus Octocanna. 



I am rather inclined, however, to consider them as 

 immature forms of Halopsis, since they bear a considerable 

 resemblance to the young of Halopsis ocellata as described 

 by Agassiz {' North-American Acalephse," fig. 14.8).

SolmaridsB. 



Solmaris sp. (?) . 



Up to the present time this genus has been regarded as 

 belonging to the southern rather than to the northern fauna ; 

 it is therefore a matter of considerable interest to find that 

 the isolated case of a young Solmaris with 15 tentacles, 

 recorded by Browne from Plymouth, has now been fol- 

 lowed by others from 52° N. lat. from deep water. The 

 ' Oceana ' specimens were all taken in hauls from between 

 1300 and 1610 fathoms. The number of tentacles varied ; 

 six individuals having 28, 32, 32, 39, 40, and 43 tentacles 

 respectively. 



Ciinantliidae. 



A Cunanthid (?) 11 millim. in diameter, with 12 tentacles 

 and large tentacle-roots, was taken between 1G70 fathoms 

 and the surface.
