34 ABT. 1. — CHARLES ELIOT : 



drawing made at Misaki and here reproduced. I did not however 

 find any specimens in the collection sent to me. 



Scyllœa bicolov Bergh. 



Eergh, Verb, k. k. Zool.-Bot. Ges. Wien 1880, pp. 167-172. 



Three specimens from Misaki. They agree with Bergh's 

 description of one caught at the neighbouring locality of Enosima, 

 except that they are much larger, being 30 mm.-35 mm. long. 

 The characteristics of this species are as follows. (1) The body 

 is dark olive green but the sole and the mouth are pinkish 

 yellow. There is a distinct border of yellow round the top of 

 the rhinophore sheaths and a less distinct one round the cerata. 

 The contrast of colours is rather striking. (2) It is probable that 

 the cerata in their natural condition have rounded edges with no 

 jags. They each bear on the inner side four branchial tufts and 

 such tufts do not occur elsewhere on the back or tail. (3) As 

 in Sc. elegantula the radula is relatively small (24x17.1.17) 

 whereas in Sc. pelagica there are more than 50 laterals. (4) The 

 teeth in the second stomach are all of one size and the liver 

 consists of 3 separate lobes. (5) The hermaphrodite gland con- 

 sists of only two lobes, which are quite distinct from one another. 

 This form is allied to Sc. elegantula (described by Bergh 

 from one small specimen obtained in the Philippines) and diners 

 from it chiefly in colour and the structure of the liver. An 

 examination of further specimens of Sc. elegantula is desirable.
