REPTILIA. 



13. Eumeces quinquilineaUis (Linnaeus). Blue-tailed Skink. One 

 specimen of this lizard was collected on the sand near Burt Lake in the 

 vicinity of the Burt Lake hardwoods, July G, 1913. This individual 

 measured 120 mm. in length. No other specimens of the skink liave 

 been taken in the Douglas Lake region. This record, although based 

 on a single specimen, is of particular interest as it moves the known 

 range of this lizard in Michigan over a degree north. Ruthven (1911 a, 

 p. 263) recorded this species from Sand Point, Saginaw Bay, Huron 

 County, and Thompson (1915, p. 4), from near East Lake, Manistee 

 County. 



11. Storeria occipitomoculata (Storer). Red-bellied Snake. Found 

 in damp woodland and less frequently in aspens under fallen timber, 

 near both Lancaster and Douglas Lakes. From five to ten individuals 

 were collected each summer. Three specimens of this snake were secured 

 at Cecil, Emmet County, August 19, 1916. 



15. Heterodon platyrhinos Latrielle. Hog-nosed Snake. This snake 

 was fairly common throughout the region but was seen most frequently 

 in the sand and aspen country within a mile of water. The hog-nosed 

 snake is evidently rather common in both Emmet and Cheboygan 

 Counties as many farmers spoke of the "Spreading Adder" when ques- 

 tioned concerning the snakes of the region. The largest specimen 

 measured by the writer was 35 inches in length. Most of the specimens 

 of the hog-nosed snake taken were in the black phase of coloring. 



16. NatrLv sipedon (Linnaeus). Watersnake. Excepting the common 

 gartersnake, the watersnake was the most common reptile of the region. 

 It was found, however, only in aquatic and semi-aquatic habitats. 

 Several large specimens have been taken in the immediate vicinity of 

 Douglas Lake and Bessey Creek. Three of these measured 37, 39 and 

 10 inches respectively. 



17. Liopeltis vernalis (DeKay). Grass Snake. This snake was rare 

 during the summer of 1913. Several specimens were taken during the 

 summers of 1914 and 1915, and nine were collected in 1916. This 

 snake was taken in the hardwoods on Burt Lake, near Sedge Pool on 

 Douglas Lake, near Bryant's Bog and on Lancaster Lake. On August
