Obs. — An examination of spirit specimens misled Humbert 

 into distinguishing Triboniophorus from Aneitea by the lack of 

 a dorsal groove, obliterated in his examples.

Obs.- — -The teeth and jaw are, as Fischer observes, not well 

 shown in Dr. Macdonald's figures. The former were probably 

 studied with too low a power, and the latter appears to have 

 shrivelled before being sketched. 



Mr. Cockerell has proposed (Proc. Z. S., 1891, p. 215, and 

 Ann. Mag. Nat. Hist. (6), ix., p. 371) to disturb our nomen- 

 clature by transferring the name "macdonaldi" to a New 

 Caledonian species, presumably hinido or modcsta, on the plea 

 that Gray's types were New Caledonian specimens. Since 

 Gray distinctly states tbat he applied the name "in recollec- 

 tion of the island where it was first discovered, and also of its 

 first discoverer," I consider that he only incidentally alluded to 

 the New Caledonian specimens, ichich were not described, and 

 that he bestowed the name on the specimens figured and 

 described by Dr. Macdonald. We may thus rigidly follow the 

 path of justice and yet escape from the confusion in which 

 Mr. Cockerell would involve us.
