112 NOTES ON HUSH NATURAL HISTORY.. 



the existing species, consists of two faces, which meet at an 

 acute angle in a transverse ridge. 



If the bones which I have found associated with these teeth 

 belong to the same animal, they seem to attest a size approach- 

 ing that of Priodon giganteus. 



The second of these genera I call Heterodon, because its 

 teeth exhibit a much greater want of conformity amongst 

 each other, both as to their shape and size, than is the case 

 in the existing armadilloes. Both the anterior and posterior 

 molars are small and conical ; while the penultimate and 

 antepenultimate are much larger, the section of the former 

 being oval and of the latter heart-shaped. The single species 

 of this genus possessed by me, is of the same size as the 

 commonest recent armadillo, Dasypus uroceras.

In the ascent from the lakes of Killamey towards the po- 

 lice-station on the Kenmare road, I turned a little out of my 

 way to see the fall of Derrycunhuey. It is very different in 

 character from O'SuUivan's or Turk, being of greater breadth 

 and volume but of less height, and having in its channel vast 

 masses of lichen-stained rock. I never saw such a profusion 

 of Hymenophyllum as grows on the stones around this water- 

 fall : the two species were completely intermixed. I spent 

 an hour searching every dark hole for Trichomanes^ but with- 

 out success. From the police-station the view over the lakes 

 is very celebrated ; but I think they lose a great part of their 

 beauty when seen from so great a height and distance. They 

 become diminutive, and you see their sinuous outline and 

 numerous islands as laid down in the maps, but the sweet 

 variety of colour, and fantastic figure of rocks, which, when 

 viewed more nearly, form so prominent a part of their attrac- 

 tions, are here entirely lost. I lingered to take a last farewell 

 of. those lovely lakes, and to smile on the legendary lore so 

 highly prized by the dwellers amid this wild scenery : no 

 mountain-summit, no shady cove, no rocky islet, but has its 

 fairy tale. The lakes themselves are clearly traced to fairy 

 origin, as the legend of Norah and Coolin abundantly sets
