NORTH AMERICAN FAUNA. 



TESTUDINATA. 



[The tortoise- shell turtle frequents the sea about the Tres Marias, 

 approaching the shores to mate and deposit eggs in May and June 

 each year. At the same time the large green sea turtle abounds along 

 these shores, where they congregate for the same purpose. — E. W. N.] 



Kinosternon integrum Leconte. 



I have no hesitation in endorsing Boulenger's view (Oat. Ohel. Brit. 

 Mus., p. 4:2) tliat the Tres Marias mud turtles are K. integrum and not K. 

 hirtipes, as held by Giinther (Biol. Centr.-Am., Eept., p. 15, pis. xii-xiv). 

 They have the broader bridge and broader jjlastron of the former and 

 agree with undoubted specimens from the mainland. The island speci- 

 mens, of which there are four adults and one young, do not differ from 

 those from Oolima, Guanajuato, Ouernavaca (Morelos), Acaponeta 

 (Tepic), Guadalajara (Jalisco), Presidio, and Mazatlan (Sinaloa), from 

 all of which localities I have examined specimens. K. hirtipes I believe 

 to be confined to the eastern side of Mexico.

LORIOATA. 



Crocodylus americanus Laur. 



JSTo specimens were secured, but Mr. Nelson assures me that the 

 crocodile occurs on Maria Magdalena Island. There can be but little 

 doubt that it is the present species which is distributed all along the 

 coast of Central America, Mexico, the West Indies, and southern 

 Florida. 



[The unmistakable furrow in the mud where a crocodile had hauled 

 up on the border of a brackish lagoon on the eastern side of Maria Mag- 

 dalena, the sight of a small head in the water, and the testimony of 

 the people on Maria Madre established the fact of their occurrence. 

 They appeared to be limited to Maria Magdalena. — E. W. N.] 



SQUAMATA. 



SAURI. 



Phyllodactylus tuberculosus Wiegm. 



This species is distributed over Mexico and Central America, and 

 has also been collected in the Cape Saint Lucas region of Lower Cali-
