Ophibolus sayi, Osceola elapsoidea, Abastor erytlirogrammus and Cycli- 

 lopliis cestivus. In addition to these, other collectors, chiefly Mr. Ken- 

 nicott, have obtained the following species in different portions of 

 Southern Illinois : — Tropidonotus woodhousi, Regina grahami, Ophi- 

 bolus doliatus, 0. evansi, Diadophis amyi, Haldea striatula, Farancia 

 abacurus, Virginia Valeria, V. elegans, Celuta helence and C. vermis. 

 Of the seven species of lizard which are known to be inhabitants of 

 Illinois, four of them (Op>hisaurus linealus, 0. ventralis, Lygosoma later- 

 ale and Ameiva sex-lineatd) are chiefly southern. Among the mammals 

 the southern Vulpes virginianus and Lynx rufus largely preponderate 

 over, if they do not replace, the northern V.fulvus andZ. canadensis. 

 There also occur Neotoma Jloridana, Hesperomys aureola, E. {Oryzo- 

 mys) palustris, and Reithrodon humilis — all emphatically southern 

 species. 



The avian-fauna of this section is as quite decidedly southern as 

 the reptilian-fauna and the flora. Mr. Allen considers twenty- four 

 species of birds as peculiar to the u Louisianian Fauna." Of this num- 

 ber only ten remain to be discovered in Southern Illinois. Few of 

 these ten species have been found so far as one hundred miles away 

 from the coast, since their distribution is governed by other conditions 

 than those of climate. They are mostly pelagic or littoral species, 

 which of course never go inland, and tropical land-birds which in 

 the United States are confined to the hot Gulf-coast. The species 

 are the following: — Puffinus obscurus (strictly pelagic); Platalea 

 ajaja, Ibis alba, Demiegretta ludoviciana, Chamtepelia passerina, 

 Quiscalus major, Picus borealis, Sitta pusilla, Helinaia swainsoni 

 (known only from Georgia and Florida) and Helminthophaga bacli- 

 manni (known only from lower South Carolina and Cuba). Of 

 these, Ibis alba and Demiegretta ludoviciana will probably yet be 

 found in Southern Illinois, since they have been traced quite as far to 

 the northward both on the Atlantic coast and west of the Mississippi. 

 Platcdea ajaja may possibly occur, since Plotus anhinga and Tantalus 

 loculator, equally characteristic of the Tropics, are quite common. 

 Picus borealis and Sitta pusilla are without doubt yet to be found 

 among the yellow pines (Pinus mitis) and red cedars (Juniperus 

 virginianus') which grow abundantly in many localities south of Wa- 

 bash County. Quiscalus major and Chamcepelia passerina are hardly 

 to be looked for, for evident reasons. The remaining fourteen have 

 already been detected, the following being the species: Peucasa aesti- 

 valis (common, breeding; known before only from Georgia and ad-
