ryetes will ultimately be found to enter the Marsupialia or not, 

 it must be a descendant out of the sain." -lock as that which gave 

 origin to the Chrysochloridida 1 . But I suspect that the brain, 

 female generative organ-, and fetal characters will turn out to 

 resemble those of Chrysochloris, as doits other characters, and 

 in that case Notorycte.s will enter the Insectivora. In this 

 order it will form a special family. Nbtoryctida'. characterized 

 hy the presence of a symphysis pubis: the CQOSSlficatiOD oi tlic 

 posterior part of the ischium with the sacrum, and perhaps 

 by the coossification of the cervical vertebra 1 . Perhaps there 

 should be added to these character-;, the fusion ot the sacral 

 metapophysis into a continuous roof, and the ossification and 

 fusion with the first rib of its hsemapophysis. 



The tritubercular molars, the large caudal intecenntra, the 

 cloacal penis, show Notoryctes to be a primitive type. As to 

 resemblances to Monotremata, such as have been suggested by 

 a recent author, none exist. On the contrary, the Notoryctid® 

 realize a desideration to mammalian phylogeny, viz : a form 

 which connects the marsupial with the placental mammalia, 

 although it is a specialized representative of this type. That the 

 insectivora are the connectant forms among placentals has been 

 long suspected and, that the connection is polyphyletic is sug- 

 gested by Notoryctes, since the Creodonta are also candidates for 

 i them to the Dasy-
