192 EEPOET ON THE NUDIBRANCHIATE 



For tlie carnivorous habits of this beautiful Nudibrancb see Alder 

 and Hancock (2) and Gosse (7). 



18. Flabellina, Cuvier. 



27. F. PUNCTATA, A. and H. 



On May llth one specimen was dredged, just over an inch in 

 length, from one mile south of the Mewstone. The rose colour of 

 the head and back was much deeper in this than in Alder's indi- 

 vidual from Torbay. The dorsal tentacles were coloured dark brown 

 along the middle third of their length, especially at the sides on the 

 lamellee ; the upper third of the tentacles was pale in colour. 



19. CoEYPHELLA, Gray. 



28. C. EUFiBEANCHiALis, Johnston. 



Examples of this species were obtained by Mr, Heape in twenty to 

 twenty-five fathoms o£E Whitsand Bay and ten miles south-east of Ply- 

 mouth, in May, 1887. We dredged two splendid specimens along with 

 a number of other Eolids on May llth this year, one mile south of 

 the Mewstone. Three more were dredged on June llth in twenty 

 fathoms, three miles south of the same rock. 



29. C. Landsbuegii, A. and H. 



I took a small example of this rare and beautiful species from an 

 Antennularia-stock dredged near the Duke Rock, in January last. 

 It was only three sixteenths of an inch long. The colour was a 

 beautiful, very transparent, pale violet, deepest on the lower part 

 of the tentacles. The hepatic caeca of the dorsal papillae were 

 orange red in colour, with numbers of small, dark brown spots. The 

 papillse were arranged in four or five clusters, very ill-defined after 

 the first set. They were very long in comparison with the size of 

 the body, the largest being as long as the oral tentacles. They 

 were not so stout as in Alder and Hancock^s individual, and were 

 capable of considerable flexion and extension. The opaque white 

 ring near the tip of the papillae was well marked. The dorsal 

 tentacles were set well apart at the base. 



This individual was kept alive for some weeks ; the heai't could 

 easily be seen beating between the first and second clusters of 

 papillae. 



Haddon (1 1) and Herdman (12) report the capture of individuals, 

 probably of this species, of much larger size.
