B. Intestine simple, without eoecum: 



"Centetinffi" (Centetes, Solenodon, Ericnhis, Echinogalc). 



"Erinacei" (Erinaceus, Chjviniira). 



"Talpinfi" {Mijocjale, Urotrichus, and other Talpids, Chrij- 



sochloris). 

 "Sorices" (Sorex). 

 1866. Haeckel places the Insectivora as the third order of the Discopla- 

 centalia, dividing the group as follows: "Subordo I. Menotyphla" . . . 

 Insectenfresser niit Blinddarm" including "1. Familia Cladobatida s. 

 Scandentia," Cladobatcs, Tiipaja; "2. Familia jNIacroscelidia, s. Salientia," 

 Macroscelidcft, Rhi/uchoci/07i. "Suliordo II. Lipotyphla .... Insecten- 

 fresser ohne Blindtlarm" . . ." 1. Familia Soricida," Sorex, Crosftopus, 

 Crocidura; "2. Familia Talpida," Talpa, Condijlura, Chrysochlorifi; 

 "3. Familia Erinaceidea," Erinaceus, Gi/mnura; "4. Familia Centetida," 

 Centetes, Solenodon. 



1867-1871 . Mivart contributes to the ' Journal of Anatomy and Physiol- 

 ogy' for 1867 and 1868 a series of important "Notes on the osteology of the 

 Insectivora." This was supplemented in an article on Hemicentetes in the 

 'Proceedings of the Zoological Society,' 1871. His revised classification 

 (1871) was as follows: 



Galeopithecid;? : Galeoplthecus. 



jNIacroscelididte : Macroscelides, Pctrodroinus, RJn/nchocj/on. 



Tupaiid.ie; Tupaia, Ptilocercus, Hijlomys [now included under Erina- 



ceidse]. 

 Erinaceidse; Gi/mnura, Erinaceus. 



Centetidfe: Centetes, Hemicentetes, Ericulus, Echinops, Solenodon. 

 Potamogalidpe ; Potamogale. 

 Chrysochloridse; Clirysochloris, Chalcochloris. 

 Talpidre. 



Subfamily 1. Talpina: Scalops, Scapanus, Condi/hira, Talpa. 

 Subfamily 2. ^Nlyogalina: Urotrichus, Myocjale. 

 Soricidae: Sorex. 



Mivart calls attention (1868, pp. 138-140) to the confusing homologies 

 of the different cusps of the molars in the Centetidfe and other families, and 

 suggests that the main internal cusp in the upper molar of the Centetidje 

 represents the "two external principal cusps of a quadricuspid molar" 

 (1871, p. 72). 



1872. Gill, in his 'Arrangement of the Families of ]\Iammals' (1872) 

 adopts the following classification :
