XXXVI. — Note o/i Pachymetopon and the Australian Species 

 of Pimelepterus. By Dr. A. GiJNTHER, Keeper of the 

 Zoological Department, British Museum. 

 The type specimen of Fachymetopon grande was transferred 

 to the British Museum when the collection of the Zoolo- 

 gical Society was broken up. Some time after the pub- 

 lication of the first description of the fish (Giinth. Fish. i. 

 p. 424) I ascertained from the MS. catalogue of the society that 

 the specimen was originally obtained by the late Sir A. Smith 

 at the Cape of Good Hope. No other individual has come 

 under my notice since ; but I have no doubt that naturalists 

 residing at the Cape would have no difficulty in obtaining 

 other examples. Fresh specimens preserved in spirits and 

 skeletons of this fish are desiderata in every museum. 



The fish described by Steindachner as Pachymetopon Guen- 

 theri (Sitzungsber. Wien. Ak. Ix. 1870, p. 135 J is also from 

 the Cape of Good Hope, and probably not specifically distinct 

 from P. grande. The characters in which this second species 

 is considered to diflfer are the proportionate length of the Jiead
