NEW NAMES FOR TWO EUROPEAN VOLES. 



The names current for two European members of the genus Pitymys 

 can not remain in use: Pitymys ibericus ft/sens, applied in L908* to a 

 Spanish animal, is invalidated by Arvicola agrestis fuscus qi Fatio, 

 L900,i a synonym of Pitymys subterraneus,i and P. selysii (Gerbe) L852§ 

 is antedated by Arvicola selysii Bonaparte L845II published as a synonym 

 of P. savii. To replace these untenable names I would suggest Pitymys 

 ibericus pascuus and Pitymys druentius respectively.

NOTE ON THE SCALES OF THE OSTEOGLOSSID FISHES. 



In these Proceedings, XX III, p. 1 1 1, I described the scales of Heterotis. 

 I am now indebted to Dr. Boulenger for a scale of Scleropages formosus 

 (or Osteoglossum formosum) from Sarawak. It is very large, about 49 

 mm. diameter, and nearly circular. The reticulated radial pattern is 

 wonderfully complete, and consists of intersecting curved lines which 

 divide the scale into small areas about 1)4 to 2 mm. in diameter, more 

 or less square, but with a corner pointing to the scale-margin. The very 

 fine circuli are moniliform throughout; it is evident that the moniliform 

 circuli distinguish the scales of Osteoglossidse from those of Mormyridse, 

 in which there is no tendency to beading. The rough greyish-brown 

 skin is as in Heterotis, and very much as in the Mormyrid Gymnarchus. 



The Eocene fossil Dapedoglossus testis ('ope, from Wyoming, shows the 

 characteristic Osteoglossid reticulation, hut in the apical field the radii 

 arc not broken up or united; so the sculpture approaches rather the con- 

 dition of the Mormyrids.
