of the back. A faint black suffusion on the throat indicates that this 

 individual is a male, and the inner surface of the thumb is brown, 

 although not yet enlarged. 



Another male (U.S.N.M. No. 75993) from Cap-Hai'tien measuring 

 50 mm. in length is much more interesting. While its head and body- 

 proportions are quite similar to those of the two already mentioned, 

 its toes are much more fully webbed — in fact, the web reaches the 

 base of the terminal disk in the fourth and fifth toes. In addition, the 

 tarsal fold in this toad is produced in a true tarsal "shovel" with a 

 narrow sharp edge. The forearm is immensely enlarged, and the 

 thumb and throat are blackened, showing that breeding was about to 

 take place. This specimen, being in better preservation than the 

 others, shows the color pattern more distinctly. The head crests are 

 edged with black, and the pustulate tubercles also have an increased 

 pigmentation. A coarsely reticulate pattern of dark on light is 

 evident on the upper surface behind the brown interocular bar, which 

 crosses the head at the posterior level of the eyes. On the upper 

 parts of the legs the dark reticulations often enlarge to form very 

 irregular dark patches, of which one on top of each tibia is especially 

 prominent. The arms bear some less definite reticulations, but there is 

 a corresponding dark spot in the middle of each forearm. The tarsal 

 and carpal regions are faintly barred with brown. The metacarpal 

 tubercles are also darkened. 



In the collection of eight adult or nearly adult toads at the Museum 

 of Comparative Zoology there is another toad from Cap-Ha'itien 

 collected at the same time as our 75993. The two are identical in most 

 respects, except that the shovel of the M.C.Z. specimen is not one-half 

 so pronounced. 



In two toads from Manneville (M.C.Z. Nos. 3101 and 3102) the 

 webs are nearly as highly developed as in the Cap-Haitien toads. 

 Three toads from Diquini and two from Momance have prominent 

 webs, but these do not extend along the sides of the toes in so wide a 

 fringe, nor are they so deeply incised, as in those from Cap-Hai'tien. 



One of the toads from Manneville has a rather irregular, wide, light 

 dorsal stripe and an equally irregular lateral stripe from the parotoids 

 to the thighs. One of the Momance toads shows the lateral stripes 

 plainly, with just a suggestion of the dorsal stripe. The black bar on 

 the forearm is a distinctive feature in all the toads. In the adults, the 

 tips of the toes and fingers, as well as all the palmar and plantar 

 tubercles, are dark brown. 



The Field Museum specimen (F.M.N.H. No. 5559) is now bleached 

 so that no trace of a pattern shows, except on the back of the hindleg, 

 where brown mottling appears. The head crests are extremely 

 pronounced. The webs are very apparent on the hind feet, while the 

 tarsal "shovel" is quite prominent. From the tip of the snout to the
