and a half. The darker lateral edges of all the scales give the ap- 

 pearance of narrow stripes. Abdominals, subcaudals, lower part of 

 head, upper labials, and rostral dull yellow or straw color. Without 

 spots. 



It is likely that in life the dark bands were purplish or bluish, and 

 the light flesh-colored. 



Total length, .65 mm.; head, .023 mm.; tail, .14 mm. Of the 

 maxillary teeth the posterior two are much the larger. 



The specimen described is No. 2255 of the alcoholic collection in 

 the Museum of Comparative Zoology. It was collected near Jackson- 

 ville, Florida, by the zoologist, Mr. J. A. Allen, to whom the species 

 is dedicated. 



The generic characters are as given by Prof. G. Jan (Arch, per la 

 Zool., Vol. in, p. 245). 



In the body and head this beautiful animal resembles the North 

 American species of the genus Calopisma ; it is sufficiently evident, 

 however, from the peculiar structure of the tail, with its carinated 

 scales, that this species belongs to Helicops. The possession of char- 

 acters belonging to both genera suggests a position for this as a lead- 

 ing species of its genus. 



Note on Aptenodytes patagonica Forst. By A. Hyatt. 



During a recent hurried visit to the British Museum, I made 

 some observations upon the specimens of this species, which may be 

 worthy the attention of the Society. The validity of Dr. G. R. 

 Gray's distinctions have been almost universally doubted, but they 

 seem to me very well founded, though not very fully stated in his 

 description of Aptenodytes Forsteri. 1 This form is represented by a 

 fine suite of specimens in the British Museum, exhibiting the young 

 as well as the adults. Some of the young equaling in size a full-grown 

 Aptenodytes Pennantii, have no orange patch on the throat, and the 

 dark area extends over the head and down the back of the neck, in- 

 terrupted in front by a spot of gray immediately under the beak. 

 This spot is separated from the gray of the neck and breast by a nar- 

 rower dark line. One specimen larger than any full-grown speci- 

 men of Aptenodytes Pennantii which I have seen, possessed the area 

 or collar extending around the neck, as in the adults, but the color 

 still remained grayish, as in the young.
