JAPANESE NUDIBEANCHS. 43 



These are perhaps young examples of H. rosea, known only 

 by one larger (55 mm.) specimen from Amboina. 



Amphorina ( ? ) sp. 



See Eliot in Journal M. B. Assoc. 1906, vii, pp. 363-366 for some remarks on tki* and 

 allied genera. 



Three specimens from Misaki, the largest about 15 mm. long. 

 The colour is greyish green, which however may be due to the 

 preserving fluid and not natural. The cerata and other external 

 characters seem to be as in Amphorina. No tentacular angles can 

 be seen on the foot. The anus is latero- dorsal. 



The jaws bear a single row of denticles. The radula is dis- 

 tinctly tapering. It consists of 70 teeth. They bear a central 

 cusp rising far back and from 2 to G lateral denticles. The 

 variation in number is due to the fact that these denticles are 

 often badly formed or split. No stylet nor any trace of arma- 

 ture was found on the verge. 



I do not think it is worth while to create a species for these 

 specimens, for they present few characteristic features. The 

 radula is that of Amphorina but absence of a stylet makes the 

 reference to this genus disputable. 



Aeolicliella japonica sp. nov. 



Five specimens. They are considerably bent but the largest 

 is as much as 50 mm. long and 15 mm. broad. All are now of 

 a uniform alcoholic yellow but the colour must evidently have 

 been very transparent in life, for the follicles of the hermaphro- 

 dite gland and the hepatic diverticula in the cerata are distinctly 

 visible through the integuments. 



The lateral margins of the foot are somewhat expanded : the 

 anterior margin in thickened and grooved but, though it projects 

 slightly at the corners, it is not produced into tentacular prolon- 

 gations: 



The rhinophores bear 3-4 strong rings, not perfoliations. It 

 is hard to say whether they are natural or the result of contrac-
