be amiss to reproduce his description.* Concerning the specific name 

 jnstiUifjcr, Dr. Liitkeu says:t "Influenced by Steindachuer's notice 

 (Wien. Sitzungsb. 187G) ou C. instUUgerj Pallas, I have sought informa- 

 tion concerning this species in the Berlin Museum ; the type is only a 

 bad half skin preserved in spirits ; Prof. Peters has been so obliging 

 as to send it to me for investigation, and I have thereby been able to 

 convince myself that the 'pistils' which Pallas describes as soft threads 

 ■with spongy heads are in reality only the half cruciform, spiny scales 

 which distinguish a certain part of the side of the body in G. tricMspis. 

 Since the name '■ pistiUiger'' is thus founded on a misapprehension, its 

 reputed priority (1811) cannot require that it be given the preference 

 over the next in the series, and we should therefore fix upon the name 

 Phohetor ventralis, Cuv. & Val." If we were to throw out all names 

 which are Ifased upon a misapprehension it would involve us in a great 

 deal of unnecessary confusion, and it would be difficult to decide how 

 far the elimination should proceed. The fact that Dr. Liitken could re- 

 cognize the peculiarity in which the specific name originated is a sort of 

 apology for its adoption hy Pallas.
