308 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



He has made observations on these five muscles with more 

 than five hundred species of birds, and presented to the so- 

 ciety a table, showing, by means of formulae, to what extent 

 these muscles are represented in their development in the 

 different families. The scheme of classification, based upon 

 these muscles, as furnished by Mr. Garrod, does not differ 

 materially from the classification hitherto adopted, although 

 our prejudices are occasionally somewhat shocked, as by the 

 close apposition of the accipitres and steganopodes. 



The general symmetry of the classification, however, is an 

 ample warrant to Mr. Garrod for insisting that whatever feat- 

 ures are adopted, myology has an equal right to be taken 

 into consideration. 12 A, IX., 291. 



AFFINITIES OF HELODERMA HORRIDUM. 



Professor Gervais has made a communication upon the 

 teeth of the American reptile known as Heloderma. A spe- 

 cies of the genus is abundant in Southern Arizona, where it 

 is called a scorpion, and is reputed by the natives to be ex- 

 tremely venomous, although experiments carefully prosecuted 

 by Dr. B. J. D. Irwin, of the United States Army, failed to ex- 

 hibit any evidence of this fact. There is, as Gervais and oth- 

 ers have found, a striking relationship between it and some 

 of the poisonous serpents in the possession of a longitudinal 

 furrow on the back part of the teeth, as if to carry poison 

 from a gland. Whether the animal be actually poisonous or 

 not, Gervais calls attention to the peculiar structure of the 

 teeth (as shown by the microscope in a cross-section), the 

 basal part of which is filled by folds, or plications, directed 

 outward, toward the fine exterior coat of enamel. 6 1>, No-

OCCURRENCE OF A CUBAN CROCODILE IN FLORIDA. 



In a communication of Mr. C. J. Maynard to the American 

 Sportsman, describing his adventures during a visit to Flor- 

 ida in the winter of 18*73-74, he speaks of the capture of 

 Crocodilus acutus on a journey from Lake Harney to Indian 

 River, at a place called Cabbage Slough. 



If he be correct in his identification, this constitutes the 

 second specimen known to have been killed in the United 

 States, the first having been taken by Professor Wyman near
