Dtdelphys [Perainys] IJieringi^ sp. n. 



Colours and proportions exactly as in D. americana, Miill. 

 ( = D. tristriata, auct), but only about half the size of that 

 species.

Head and body 77 raillim. ; tail 43 ; hind foot 14 ; ear 6*3 ; 

 skull, basal length 22'o ; first three molars, length 4*2. 



Hah. Rio Grande do Sul [Dr. H. von Ihering). 



Didelphys [Peramys] Henselij sp. n. 



Size intermediate between that of the D. hrevicaudata and 

 the D. sorex and Iheringi groups. Colour dark grizzled grey 

 along the whole upper surface, deep rufous on the sides and 

 belly. Ears small, reaching when laid forward only halfway 

 towards the eye. Mammae about twenty-five in number, five 

 central, and about ten pairs of lateral ones. 



Dimensions of the type (an adult female, in spirit) : — 



Head and body 106 millim. ; tail 62 (extreme tip imperfect) ; 

 hind foot 15"5 ; skull, length 27 ; three anterior upper molars 

 4-4. 



Hub. Rio Grande do Sul [Dr. H. von Ihering). 



This is no doubt the intermediate species described but not 

 named by Hansel *, and I have therefore, at the suggestion of 

 Dr. von Ihering, named it after that eminent raammalogist.

Note on Lophopus Lendenfeldi. 



To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, — The facts narrated in the letter of Mr. Whitelegge at 

 p. 62 of the January Number of your Journal have been also brought 

 to my notice in detail in a letter from himself, and more generally 

 in one signed by two gentlemen, Messrs. J. Douglas Ogilby and 

 John Brazier, F.L.S., whom I understand to be members of the staff oT 

 the Australian Museum, Sydney; and I have before me a printed 

 extract from the ' Ashton Keporter ' of March 20th, 1886, de- 

 scribing in general terms a fine Polyzoan and a method of preserving 

 it in such a way as to show the parts much as those of the specimen 

 described by me as Lophopus Lendenfeldi in the ' Journal of the 

 Linnean Society ' (Zoology), xx, p. 62, pi. ii. It may be almost 

 unnecessary for me to say that I was in total ignorance of these 

 facts when I wrote my paper, but such is the case ; and I regret 

 very greatly the injustice which I have thus unconsciously done to 

 Mr. Whitelegge, who has fully vindicated his title to the honours of
