112 MICHIGAN SURVEY, 1905. 



snake has been listed from the Lower Peninsula,* but I have never seen 

 a specimen from southern Michigan that could be definitely referred to this 

 variety. Sirtalis forms with a varying amount of red on the skin between 

 the lateral spots are often found about Ann Arbor, but the amount of red 

 is so small that it is generally more satisfactory to classify the specimens 

 with the typical form. During the past summer, howeyer, three specimens 

 were taken on Isle Royale, II, III, that strikingly resemble specimens from 

 Colorado and Washington and can only be referrefd to the variety. 

 The dorsal row of spots, as in typical specimens of the variety, are fused 

 into a band along either side of the dorsal stripe, which is united below with 

 the row of spots above the lateral stripes. Between the scales the skin is 

 Orange Red Tint No. 1 (using Milton Bradley colors). One of these is a 

 female containing 28 embryos not yet mature, as a large yolk body is present. 



5. Thamnophis saurita (L.). Riband Snake. There is a record in the 

 University Museum Catalogue, Vol. 2, p. 196, of a specimen (No. 7452) of 

 this snake taken on Isle Royale by Dr. Foote, which I have been unable to 

 verify. 



6. Chrysemys marginata Agassiz. Painted Tortoise. A number of 

 specimens were taken on Carp river, IV. 1, in the Porcupine Mountains in 

 1904. It is also reported from Marquette by Dr. Downing.
