Notes on Cnonmbers. 



The following are some of the notes made September 5th, upon 

 the specimens shown in Plate IV., taken in order, beginning with 

 the first : 



Number 1. Is a short, roundish specimen, peculiar in having a 

 surface much mottled with white, and the blossom end quite pointed 

 and ribbed with white. Nearly spineless. 



Number 2. Is remarkable for its large spines, somewhat curved, 

 rather uniform in size throughout, and decidedly triangular in cross 

 section. Very green at stem end, and quite pale-green and ribbed 

 with white at the blossom end. 



Number 3. Is somewhat similar to No. 2 in the number of spines, 

 but is a greenish-white throughout, somewhat curved, and decidedly 

 triangular in cross section, and larger at the stem end. 



Number 4. Is with few large spines, very straight and plump and 

 rather short. A light-green, strongly ribbed with white from the 

 blossom end. 



Number 5. Has very few small spines. Is larger at the blossom 

 end. A pale-green throughout, with the exception of a tendency to 

 be white-ribbed from the blossom end. 



Number 6. Is white throughout, with few spines, very plump and 

 slightly curved. 



Number 7. Is remarkable in being exceedingly spiny. Dark-green 

 at stem end, growing pale and becoming yellowish-green at the blos- 

 som end, with a tendency to be ribbed and quite triangular in cross 

 section. 



Number 8. Is nearly the shape of No. 1, but, in addition, is ex- 

 ceedingly spiny, with a strong tendency to mottling, with a light 

 green, quite sharp-pointed at the blossom end. 



Number 9. Is nearly free from spines. Is broadly boat-shaped, 

 with large blotches of whitish-green upon the green background, with 

 a tendency to be ribbed from the flower end. 



Number 10. Is with few spines, and a deep green color through- 

 out. Strongly triangular in section. 



Number 11. Is free from spines, oval-shaped, and white throughout. 



Number 12. Is somewhat spiny, long, dark-green, and somewhat 

 club-shaped. 



Number 13. Is almost without spines, and white throughout. 

 Very broadly boat- shaped, nearly straight, and very handsome.
