The unfortunate nomen nudum L. profunda of 



Totton (1936, p. 235) refers to specimens of L. multi- 



cristata Moser from Bermuda (Beebe Collection).

Surf art 



Lensia conoidea Keferstein & Ehlers, 1861. 



Bigelow & Sears (1937) published some fine figures 

 of this species and valuable further notes. Their 

 figure (fig. 35) shows the apical view of the posterior 

 nectophore, but I find that in specimens from off the 

 Irish Coast, from 'Discovery' Station 100c, and from 

 ' Manihine ' South-west Ireland Station 4, the apico- 



ventral corner of the right hydroecial wing is not like Text-fig. 56. Lensia conoidea. Apical view of posterior 



the left one, which is figured correctly. The right one nectophore, x 34, to show the correct shape of the artic- 

 is of a square section as shown here in Text-fig. 56. 



ulating surfaces. 'Manihine', South-west Ireland, St. 4. 



Lensia subtilis var. (Chun), 1886. 



Quite arbitrarily I am referring to fourteen specimens (Text-fig. 57 B, C, D) as a variety of this 

 common species. They come from 'Discovery II' Stations 1585-7. The stalks of their somatocysts 

 are relatively longer than in L. meteori (Text-fig. 60), and the wall of the hydroecium instead of being 

 nearly vertical for most of its extent as in L. meteori, lies at 45 and more nearly approaches the 

 condition found in L. subtilis. I report these specimens under the name subtilis var., pending the 

 discovery of more specimens and hesitate to set up a new species. It may be significant that from 

 'Discovery II' Stations 1585 and 1586 at which eight of these intermediate type specimens were 

 taken no other specimens of L. subtilis were found. Also at 'Discovery II ' Station 1587, where two 

 specimens of L. meteori were found as well as several of this intermediate type, again no other 

 specimens of L. subtilis were found, although L. subtilis was common at most stations off the East 

 African coast. The fourteen specimens were found at a rather greater depth than those of L. meteori, 

 but there may be no significance in this. 



I give sketches of six anterior nectophores of L. subtilis from Aqaba for comparison 

 (Text-fig. 57 A).
