180 APPLICATION OF THE NAME TEUTHIS—GILL. vol.xvih. 



was described from a specimen of the West Indian A. chirurgns, which 

 was recorded l)y Dr. Giinther^ in 1861 as being then in the British 

 Musenm.

The name Teuthis was introduced in the twelfth edition of the Sys- 

 tema Natnra; by Linnseus ^ as a substitute for Hejyatus, and in fact liis 

 kno\\ ledge of the group so called was originally chiefly derived from 

 (irouow. From misapprehension as to the position of the ventral lins, 

 he referred it to the "Pisces Abdominales" between Silurns and 

 Loricaria, and it must be here recalled that he had already recognized 

 thiee siiecies of Acanthurids which he associated with theCh.etodons, 

 viz: C. (10) nigricans, G. (12) lincafns, and C. (13) friostegus. Had it 

 not been for the misapprehension, he would doubtless have referred 

 his species of Teuthis also to Chatodon. Linmeus was inferior as an 

 ichthyologist to both Artedi and Gronow, and the only reason for 

 rejecting the earlier and adopting his later name for a genus, is because 

 the binomial nomenclature was not adopted by Gronow in the work 

 cited. Accepting, as we do, these principles, Ave commence with Lin- 

 njvus, and first have to iiupiire what that naturalist actually meant. 

 All that is published in the twelfth edition of " Systema Natura^"^ 

 couceiiiing Teuthis is here rei)roduced, it being recalled that the genus 

 was referred to the Pisces Abdominales.
