In the Proc. Koy. Soc. Edinb. 1889-90, pp. 397, 398, I 

 have given my reasons for referrincrthe original lihadinichthys 

 Ge.ildei to Hh. cariimtus, Ag., and also for believing that the 

 Eskdale fish is a distinct species, for which the terra elegan- 

 tulus, which I had used to designate a variety, must now 

 be adopted. From this species I can no longer separate Bh. 

 delicatulns. 



Acroleins ortholejns^ Traq.

The Edinburgh Museum possesses a splendid specimen of 

 a large Palaioniscid, 25^ inches in length, which, from the 

 scale-ornament, I must refer to the same species as the fi.sh in 

 the British Museum to which six years ago I gave the name 

 of Eloniclithys ortholepis. in the present specimen, however, 

 the great thickness of the scales, along with their shape, 

 indicate that its position is in Acrolepis, a position corrobo- 

 rated by the absence of serrations along the posterior margins 

 of the scales. The original ^^ Ehnichthys " ortholepis is, it 

 may be added, an immature example 12 inches in length. 



Sfyracopterus fulcratiiSf Traq . 

 Holurus fulcratus, Traq. Trans. Roy. Soc. Edinb. xxx. p. 4G. 



The original specimen of Holurus ficlcraius, Traq., in the 

 collection of the Geological Survey of Scotland is a mere 

 fragment. By a mistake its locality was given as Glen- 

 cartholm, whereas it was in reality found at Tarras Foot. 



The Geological Survey ofticcrs have since acquired a number 

 of additional specimens from the same locality wiiich show 

 that the species does not belong to Holurus^ but to a new 

 genus closely allied to Benedenichthys *, Traq., from the 

 Carboniferous Limestone of Belgium. As these specimens 

 belong to the Survey, I must defer their description to the 

 forthcoming second part of the " Report."

 preoccupied, I propose to alter it to liencdtnichthus, and at the same time 

 to state that 1 nave become convinced that, though it presents many re- 

 eemblunccs to the I'latysoniidjr, it is after all m.ne Pnla^i^niscid. and should 

 be resturod to the family Pahvoniscidie.
