Type: Theridomys? blainvillei Gervais, * from Issoire, Puy-de-Dóme, France. ‘‘M. 
Bravard avait nommé ce genre Blainvillinys dans son catalogue manuscrit; 
mais je ne crois pas que ce nom puisse étre adopté, pas plus que celui de 
Cuvierimys. La construction de l'un et de l'autre est trop peu conforme aux 
rógles suivies en nomenclature; c'est pourquoi j'ai laissé provisoirement l'espéce 
qui lui sert de type parmi les Théridomys." (GEnvars, l. c., 1848-52, p. 4.)
