Pseudacris nigrita triseriata (Wied), Striped Chorus Frog.—Lyon Co.: 10 miles south of Plymouth; 3 miles north of Emporia (No. 300); 7 miles west of Olpe; 2 miles northeast of Emporia (Nos. 434-441).* Neosho Co.: 3 miles west of Erie.

Hyla versicolor versicolor (Le Conte), Common Tree Toad.—Chautauqua Co.: Elk City (No. 621).

Rana catesbeiana Shaw, Bullfrog.—Ness Co.: 4 miles west and 1.5 miles north of Ness City (No. 607).* Wallace Co.: 3 miles east of Sharon Springs (1 spec.).*

Rana pipiens brachycephala Cope, Leopard Frog.—Clark Co.: 11 miles south of Bucklin (Nos. 398-400).* Ness Co.: 4 miles west and 1.5 miles north of Ness City (Nos. 505, 508, 509, 608).*

Rana sylvatica cantabrigensis Baird, Wood Frog.—Lyon Co.: extreme southwestern corner, 3 miles east of Chase County line, between the Verdigris River and the corner of the county (1 specimen, now Mus. Nat. Hist., Univ. Kans., No. 23149).* This specimen provides for the first time a basis for inclusion of the species in the fauna of Kansas. It measures 50 mm. snout to vent; hind leg from vent 80 mm.; tibia 23 mm. The ratio of hind leg to snout-vent measurement is 0.625, and that of the tibia to snout-vent measurement is 2.17. Both figures are too high for Rana s. sylvatica, in which the former ratio varies between 0.53 and 0.62, the latter ratio between 1.6 and 1.88. The ratios agree well with those of R. s. cantabrigensis, in which the former ratio varies from 0.62 to 0.75, the latter from 1.93 to 2.3. Direct comparison of the specimen with typical examples of both subspecies substantiates its allocation to R. s. cantabrigensis.

In the vicinity of Kansas, specimens of this species are known from Missouri (St. Louis and Stone Counties only) and northwestern Arkansas (Washington County: Winslow and Prairie Grove, Mus. Nat. Hist., Univ. Kans., Nos. 16526, 18820, 18823). Reëxamination of these specimens confirms their identity as Rana sylvatica sylvatica to which the Missouri specimens from Stone County undoubtedly also belong. Accordingly this race is still to be anticipated in extreme southeastern Kansas.

Reference of the specimen from Lyon County to Rana s. cantabrigensis presents a problem in distribution, for the race is not known from nearer Kansas than North Dakota, Minnesota, Wisconsin and southern Illinois, except for a record given by Cope (Bull. U. S. Nat. Mus., No. 34:437, 1889) from "western Missouri." Hurter (Trans. St. Louis Acad. Sci., 20:123, 1911) restricts this record to Cooper County, and presumably verifies Cope's identification. Hurter, too, recognized the other form, R. sylvatica, in Missouri (Marble Cave, Stone County). Cope distinguished between the two races (as they are now recognized) and recorded typical R. sylvatica from St. Louis. Accordingly the specimen from Cooper County may be considered properly identified racially. It apparently is from the locality nearest to Kansas at which the race has been taken.

It seems highly probable that the Kansas occurrence, and possibly those in Arkansas and Missouri also, is a relict one. It is highly improbable that the species has a continuous distribution in either state. A wider or more southern distribution in the past seems evident. The group to which it belongs certainly has had a more southern range, as indicated by Taylor's discovery in Meade County, Kansas (Univ. Kans. Sci. Bull., 28:217, 1942), of a fossil species of Rana (parvissima), from the Upper Pliocene, presumably related to sylvatica. It may or may not have been a direct ancestor of the living species.
