Hematonycteris LYDEKKER, Zool. SEC for 1896, X XXIII, Mamm., p. 23, Index 
new genera, 8, 1897. 
Provisional name for a specimen of Diphylla ecaudata from Brazil, in the Berlin 
Museum, described by Dobson (Cat. Chiroptera Brit. Mus., 551, 1878). ‘‘ The 
Berlin form is either anomalous as to the number of the upper incisors 
or is a type of a separate genus. It is most likely the former.... I, 
however, comparisons should not sustain this reference, the name Hazma- 
tonycteris may be assigned the form described by Dobson." (H. ALLEN.)

heim [Rhein-Hessen, Germany], wird ein eigenes, zwischen der Halicore 
( H. dugong) und dem Lamantin ( Manatus) stehendes Genus pflanzenfressender 
Cetaceen bilden, für das ich den Namen Halianassa, Seekónigin, passend finde 
Ich bezweifle nicht, dass De Christols Halicore Cuvieri . . . und als dann 
auch Cuviers Hippopotamus medius und H. dubius so wie mein Manatus studeri 
dazu gehóren, wesshalb ich das Thier Halianassa studeri nenne."

* Les Cétacés EE vores **ont deux mamelles sur la poitrine et . . . qui de loin, 
quand ils font sortir verticalement leur partie antérieure hors de l'eau, ont pu leur 
faire trouver quelque ressemblance avec des femmes ou des hommes et ont probable- 
ment donné lieu aux récits de quelques voyageurs qui prétendent avoir vu des tritons 
et dessirénes." (Cuvier, Regne Animal, 2e ed., 283, 1829.)
