the forms from these islands it seems useless to attempt to affix a specific name 

 to it. The specimen from Makemo Island is a little larger, hut has become 

 dried and shrivelled so that its determination is even more uncertain.

21. Moschites rotunda. 

 Eledone rotunda Hoyle, '86, p. 104, Plate 8, Figs. 4-6. 



Habitat — ^ia.ium 3398, off Cape San Francisco ; March 23, 1891; lat. 1» 7' 

 N., long. 80° 21' W., 1573 fathoms ; green ooze ; temperature, surface 84°, 

 bottom 36° ; one specimen 9 , No. 7951. [H. 44.] 



With some little hesitation I regard this little species as the young of a 

 species discovered by H. M. S. " Challenger " in the Pacific and Southern 

 Oceans. The only points of difference are : (1) there is a shallow depression 

 in the middle line below, (2) the mantle-opening terminates immediately be- 

 low the eye, (3) the umbrella is proportionally better developed, and (4) the 

 eyes are comparatively larger. Some of these are known to be characteristics 

 of youth, and I do not think that they justify me in creating a new species for 

 what is undoubtedly a young specimen. 



22. Moschites verrucosa. 



Eledone verrucosa Verrill, '81a, p. 105, Plates 5, 6. 

 Eledone verrucosa Hoyle, '86, p. 104. 



Habitat. — Station 3393, off Cape I\Iala ; I\[arch 10, 1891 ; lat. 7° 15' X., 

 long. 79° 36' W., 1020 fathoms; green mud; temperature, surface 74°, bottom 

 36. °8 ; three specimens 9 » two badly macerated. No. 7940. [H. 95-97.] 



The only one of these specimens which was in reasonably good condition 

 agrees very well with Verrill's description. The eyes are rather more swollen 

 than in his figure, and the tubercles covering them are uniform in size. Ver- 

 rill states that in his female they were smaller than in the male, and as the 

 present e.xample is only one-thiid the size of his, this may probably be due to 

 incomplete development.
