THE recent descriptions of new salamanders, Eurycea tynerensis Moore and Hughes, Eurycea griseogaster Moore and Hughes, and Typhlotriton nereus Bishop, prompted the writer to collect and study salamanders in the Ozark uplift in northeastern Oklahoma. The observations presented herein are mainly from northeastern Oklahoma although interesting notes from other regions of the state are included. Some specimens were placed in the University of Oklahoma Museum of Zoology. Some were presented to Dr. G. A. Moore, and the remainder are in the writer's personal collection. Ambystoma maculatum (Shaw).-An egg mass collected Feb. 28, 1944, in an overflow pool of a small spring fed strealh 2 miles south of Scraper, Cherokee County, was taken to the laboratory where the larvae began emerging on March 10. Unfortunately these larvae failed to survive but others were collected later (Mar. 28, June 11, 16, and 25) in abundance. On June 16 metamorphosing larvae were found and carried to the laboratory where they developed the adult color pattern in sufficient detail by June 27 to confirm their identification as A. maculatum. A thorough search for adults and newly metamorphosed individuals in the vicinity of the pool was futile. Ambystoma texanum (Matthes).-Large numbers of this secretive species were taken from beneath logs in a shallow slough 2 miles south of Norman, Cleveland County. Males taken here as early as December 4, 1942, had greatly enlarged testes which contained active spermatozoa. On February 28, 1942, eggs were collected. At the same time larvae about 8 mm. in length were seen swimming in the slough. Several specimens from Osage County, 3 miles northwest of Tulsa, represent a new locality record. Ambystoma trigrinum mavortium Baird.-Neotenic individuals of this species were taken April 24, 1942, and June 9, 1943, in a cattle tank 6 miles east of Norman, Cleveland County. In April terrestrial adults were found in the same pool. Neotenic males taken in April had enlarged testes containing active spermatozoa. The only previous report of neoteny in mavortium is from Estes Park, Colorado (Gadow, 1908). The new Cleveland County record is 500 miles southeast of Estes Park and at a considerably lower elevation (1200 ft m.s.l.). This suggests that neoteny in mavortium may be considerably more widespread than previously suspected. Plethodon cinereus angusticlavius Grobman.-A specimen taken 2 miles south of Scraper, Cherokee County, on April 27, 1945, appears to be the first record from Oklahoma. It was found beneath moist leaves in a narrow stream valley in rugged limestone hills. Another specimen was collected in Adair County, 5 miles south of Kansas, on March 28, 1944.
