248 INDEX GENERUM MAMMALIUM. 
B 
Eboroziphius Lemmy, 1876. Cete, Physeteridie? 
Proc. Acad. Nat. Sci. Phila., July 11, 1876, 81; Journ. Acad. Nat. Sci. Phila., 2d 
ser., VIII, pt. m1, 224-226, pl. 30 fig. 5, pl. 31 fig. 3, 1877. 
Type: Kboroziphius coelops Leidy, from the phosphate beds of Ashley River, 
South Carolina. 
Extinct. Based on a beak. 
Eboroziphius: Lat. ebur, eboris ivory; +Ziphius. 
Echidna G. Cuvier, 1798. Monotremata, Tachyglosside. 
Tableau Elément. Hist. Nat. Anim., 143, 1798; Lecons Anat. Comp., I, tabl. 1, 
1800. 
Type: Les ‘fourmiliers épineux’ (= Myrmecophaga aculeata Shaw), from New 
South Wales, Australia. 
Name preoccupied by Echidna Forster, 1788, a genus of Pisces. Thomas (Cat. 
Marsup. & Monotrem. Brit. Mus., 377, 1888) has claimed that the name was not 
preoccupied, as no species was mentioned as the type of Forster’s genus, and the 
description is unrecognizable, it being thus virtually a nomen nudum. Later 
he admitted that the name was preoccupied and adopted Tachyglossus. (See 
Ann. Mus. Ciy. Storia Nat. Genova, ser. 2*, X VIII, 621, 1897.) 
Echidna: £yi8 va, adder, viper—probably from the sharp spines, which are sup- 
posed to prick like the fangs of a viper. 
Echimys (‘Grorrroy’) Cuvier, 1809. Glires, Octodontide. 
Cuvier, Nouv. Bull. Soc. Philomathique, Paris, No. 24, 394, Sept., 1809; Drsma- 
REST, Nouv. Dict. Hist. Nat., nouv. ed., X, 54-59, 1817 (includes 7 species); 
ALLEN, Bull. Am. Mus. Nat. Hist., N. Y., XII, 262, 263, 1899 (type fixed). 
Echymys (‘JouRDAN’) WiEGMANN, Archiv Naturgesch., 1838, II, 389 [395]. 
Echinomys W ^GNER, Abhandl. Akad. Wiss. München, III, 203, 1840; Suppl. 
Schreber’s Sáugthiere, I[I, 339, 1843. 
Echiomys W AGNER, Wiegmann's Archiv Naturgesch., 1841, Bd. 1, 121. 
Enchomys GrtoaER, Hand- u. Hilfsbuch Naturgesch., I, pp. xxxi, 100-101, 1841. 
Based on the ‘Lerot à queue dorée ( Echimys cristatus Desmarest), from Surinam; 
and the ‘ Rat épineux’ of Azara ( E. spinosus Desmarest—type), from Paraguay. 
Echimys: éxivos, hedgehog; 0s, mouse (in analogy with 2y:687«r0s; see also 
note under Zchiothrir)—in allusion to the bristly spines which are mingled 
with the pelage. 
Echimys I. Grorrroy, 1838. Glires, Octodontide. 
Écho du Monde Savant, Paris, 5* Ann., No. 349, p. 201, July 7, 1838; Ann. Sci. 
Nat., Paris, 2* sér., X, 124, Aug., 1838; Mag. de Zool., Paris, 2* sér., 30, 1840; 
ALLEN, Bull. Am. Mus. Nat. Hist., N. Y., XII, 260, 264, 1899. 
Type: Echimys setosus Desmarest, from South America. 
Echimys Geoffroy is not the same as Echimys Cuvier, 1809, the latter being based 
on E. spinosus. Allen has renamed Geoffroy’s genus, Proéchimys, taking E. tri- 
nitatis as the type. 
Echimys: éxivos, hedgehog; “ts, mouse—‘spiny rat,’ on account of the bristly 
pelage, which has spines mixed with the fur. 
Echinodes (‘ Pome.’ ) TrovEssart, 1879. Insectivora, Tenrecide. 
TRovEssART, Revue et Mag. de Zool., 3° sér., VII, 274, 1879; Cat. Mamm. Viv. 
et Foss., Insectiv., 56, 1879; Covzs, Century Dict., II, p. 1832, 1889. 
Trouessart gives *'Echinodes Pomel, 1848 (sine caract.)" in the synonymy of 
Hemicentetes; but Pomel only uses the name in a tribal or supergeneric sense 
in the form Echinoidea in the paper quoted ( Biblioth. Univ. de Genéve, Archiv. 
Sci. Phys. et Nat., IX, 251, Nov., 1848). Coues considers it the ‘‘same as 
Hemicentetes.”’ 
Name preoccupied by Echinodes Le Conte, 1869, a genus of Coleoptera. 
Echinodes: éxtv óc, like a hedgehog, prickly; <éyivos, hedgehog; €760s, form.
