XXVII.-Furtlu:'1' Notes on tlie Genus Chiroderma. By OLDFIELD THOMAS. Tr-rn following points with regard to the Chiropterous genus Chiroderrna have arisen out of the publication of Dr. H. vVinge's ' Bats of Lagoa Santa ' * and of Dr. H. A 11en's remarks on the genus in connexion with the description of his Vamp,IJrops zarlzi'nzts t. In the first place, my own remarks on the genus itself seem to have been unaccountably misunderstood by the latter author, for, for from "claiming that Oltiroderma is not distinct from Vampyrops," I maintained, in the paper criticized by him t, that it was a perfectly distinct genus, and gave it a. place in the synopsis of genera on p. 170, although at the same time two species referred by Dr. Dobson to Ohirodenna were transferred to Vampyrops. Nor do I by any means '' acknowledge that the nasal cleft disappears in old indivi duals," as Peters's statement to this effect was not accepted in my paper and was explained away in the last paragraph of p. 1G9. One mistake in my paper, however, I should like to correct more prominently than I have hitherto done, namely.as to the spelling of the new species there described. This should be Vampyrops Caracciolz·, instead of V. Oa1·acciolce, the mistake having been clue to a mi::;conception as to the name of the discoverer, 2ilr. Caracciolo, whose proper name is now well *'J ordfundne og nule,·ende Flagermus fra Lagoa Santa, l\Iinas Geraes -E l\Ius. Lundii,' 1892. t Proc. Ac. Philad. 1891, p. 400. +Ann. & :i\fng. Nat. Hist.

Again, in 1S91 I had the opportunity of describing* a Stenoclermatons Lat, this time of the genus Oltiroderma itself. That description was based on the :Minas Gentes specimen called in Dobso11,s Catalogue Cltfroderma villos11,1n, Peters; and reasons were shown why it should be looked upon as distinct, and the name 0/1. Doriro was given to it. In the contrasted descriptions of the teeth of the two forms on p. 882 two important misprints have crept in, which, although they might be detected on a careful reading of the whole paper, yet, placed in so promiuent a position, might easily deceive any one working on the su�ject. The mi::itake consists of the transposition of the dimensions of the posterior teeth of Oh. Doria! and 0/i. villosum, so that each is made out to have the dimensions of the other. The erroneous lines should therefore read :- G/1. Dorice. Posterior upper premolar l Larger, combined and two molars ...... f length 7·4 llllll. Posterior lower premolar l Combined length and two molars ...... f 8-2 mm. Ch. 1•illosum. Smaller, combined length O·O mm. Combined length (}3 mm. Th2nks to the kindness of Dr. II. vVinge, the National Collection ltas now obtained from the Copenhagen Jlu;-;enm a number of the specimens from Lagoa Santa do3cribecl by him in the valuable paper quoteJ above. Among these there is a specimen called by him Cl1iroderma uillosum, apparently in ignorance of my paper, for on examination this proves, as might be expected from its locality, to be an example of 0/i. Doriro, agreeing in every respect with the type, except that its outer incisors arc rather shorter, perhap:1 owing to greater wear. This very species, according to Dr. \Vinge, was the one termed by LunJ "Phyllostoma dorsale," but without description; so that my own much later name will still have to stand for it. The full synonymy of the l\Iinas Gemes species will therefore be:- 012£,·oderma Dorim. Phyllostovut dorsale, Lund, lllik Ilras. Dyrev., Dansk. Afh. ix. p. 200 (1842) (nom. nudum).
