156 Schiodte's Specimen 



The predominant part, which articulate animals perform, all 

 over the world, in the terrestrial and fresh-water Fauna, corre- 

 sponds with the fact, that most of the cave inhabitants belong to 

 that series ; while the small number of species, and even of indi- 

 viduals, is easily explained by the poverty of the locality, as re- 

 gards the conditions favourable for organic life. But if we recollect, 

 that only a few caves have been visited zoologically, that only few 

 naturalists have examined them, and finally, that the animals of 

 the caves of Carniola, which I have described above, were found 

 in the course of half a score days only, and in but one season, we 

 may look upon it as probable, that the number of cave-animals, 

 even those of the caves hitherto actually visited, is far from being 

 exhausted.

The following observations have been communicated by the author, in 

 a letter to Dr. JVallich, as an Appendix to the above Memoir : — 



I. I have mentioned a peculiar insect of the family of Locusts 

 as occurring in the caves of Carniola, and in grottos in the vicinity 

 of Syracuse ; but I could not do more than barely mention the spe- 

 cies, not being in possession of completely developed specimens. I 

 have since learned that the animal has been already described. 



In a paper of Dr. H. Fischer (Beitrage zur Geschichte des 

 Orthopteren-Studiums, in Entom. Zeitung, 10 Jahrg. Feb. 1849, 

 p. 44) I was made aware of the existence of a memoir, which ap- 

 pears to have remained in complete obscurity even in Germany 

 itself, but in which the insect in question is clearly described under 

 the name of Locusta cavicola. The author is Vincent Kollar; the 

 memoir is in " Systemat. Verzeichniss der im Erzherzugthume 

 Oestreich vorkommende geradefliigeligen Insecten," and is also in- 

 serted in " Beitrage zur Landeskunde Ostreichs unter der Enns," 

 3d vol., Vienna, 8vo. p. 67. The insect was discovered by Director 

 Schreibers in a small cavern in the vicinity of Baden, called the 

 Schelmenloch.
