JAPANESE NUDIBRANÇHS; 31 



marked and bears 4 or 5 bipinnate processes on either side, 3 in 

 front of the branchiae and one or two behind them. The fifth 

 process is rudimentary and in one specimen hardly visible. The 

 branchiae are rather scanty, in one specimen five, in the other 

 fonr. Bat in this latter one plume is bifid and apparently re- 

 presents two which have grown together. 



The labial armature consists of two yellow, separate, triangu- 

 lar plates composed of rather fibrous rods which are not very 

 distinct individually, although the plates are distinct enough. The 

 formula of the radula is in one specimen 23x18 + 3.0.3 + 18 and 

 in the other 18x14 + 3.0.3 + 14. The teeth are yellowish brown 

 and shaped as described by Bergh for E. croceus. The vas 

 deferens and glans are armed with spines of varying shape but 

 mostly hamate. 



It is hard to believe that this is not the E. japonicus of 

 Bergh described from Japanese specimens, but at the same time I do 

 not see that it possesses any characters which decisively separate 

 it from E. croceus, especially from the variety capensis. The 

 coloration is possibly different and notes on the living animal 

 would be valuable. The radula of E. croceus is very variable and 

 ranges from 18 + 3.0.3 + 18 to 35 + 3.0.3 + 35. E. japonicus has 36 

 or 37 + 3.0.3 + 36 or 37. 



Kalinga oniata A. and H. 



See Eliot, P. Z. S. 1906, p. 670-673 and authorities there quoted ; Bergh on Opisthobran- 

 chiata of S. Africa in T. South Afr. Philos. Soc. Vol. xvii, 1907, p. 75. 



One specimen from Moroiso, accompanied by a rough 

 drawing according to which it was, when alive, about 60 mm. 

 long and 35 mm. broad, yellowish white in colour and bearing on 

 the back about 40 projections or papillae of a light red colour. 

 The teeth are extremely small and cannot be seen separately 

 even under a hand lens. Under a high power they prove to 

 agree with previous descriptions. The other external and internal 

 features are as usual. As often happens in this species the buc- 

 cal parts are completely everted.
