There was a striking contrast between the two specimens ! The 

 head of the female was regular in outline, comparatively smooth, 

 teeth white, regular and sharp, plates even in surface and contour, 

 and colors very marked. The entire under surface of both speci- 

 mens was pale yellow, shading gradually darker up the sides with 

 fine irregular streaks and spots of black. On the upper parts of 

 the female through the entire length the black and yellow mottling 

 was about uniform, the yellow rather predominating. The general 

 appearance of the female was decidedly yellowish, while the back 

 and tail of the male showed an almost entire absence of yellow, 

 the prevailing color being a leaden, lustreless black. In brightness 



male greatly outranked her rough and burly lord. The stomachs 

 of both specimens were quite empty, but in the {esophagus of the 

 male were the torn remains of two mud-hens in a state of disgust- 

 ing decomposition. The ovary of the female contained four hun- 

 dred and twenty eggs, varying from the size of No. 8 shot to a 

 hen's egg, all perfectly spherical. 



The exact locality of the captures was a narrow, very deep and 

 crooked stream known as Arch Creek, flowing from the Everglades 

 into the head of Biscayne Bay. While at Biscayne I collected 

 abundant evidence that crocodiles, though rare, exist in various 

 tributaries of the Bay. On the bank of Arch Creek, I found the 

 skull, fifteen inches long, minus the lower jaw, of a crocodile be- 

 longing to the same species as the large specimens. No one could 



I succeeded in getting the perfect skull of a small specimen 

 killed a few weeks before in Indian Creek, on the east side of the 

 bay, quite near the seashore. Its length from occiput was seven 

 and one-half inches. I was shown a small stuffed specimen four- 

 teen and one-half inches in length, captured September 26, 1874, 

 :it the mouth of .Miami River, ten miles farther down the bay. All 



half the time, being influenced by the tide. Brof. Ward has re- 

 cently received a crocodile (skin and skeleton) from Lake Worth, 

 Florida, ninety miles north of Biscayne Bay, which is of the same 

 species as the foregoing. The skin measures nine feet ten inches. 



In determining the species of these specimens I follow the late 

 Dr. J. E. Gray, of the British Museum, as the best recent authority, 

 his synopsis of recent crocodilians being the latest, most minute
