OF THE GALAPAGOS ARCHIPELAGO. 501 
3 (Indefatigable Island) nigricanti-cinereus, fere unicolor, dorso et alis extus rufes- 
cente oleagineo perfusis, hypochondriis imis et tectricibus caude inferioribus obsolete 
albo notatis, alis extus, dorso postico et uropygio interdum eodem modo ornatis: iride 
coccinea: pedibus olivaceo-brunneis: rostro nigro: long. tota 5:0, ale 2-6, caude 1-0, 
tarsi 0-9, rostri a rictu 0°75. 
Obs. Sp. P. jamaicensi similis, sed nucha omnino nigricanti-cinerea et maculis dorsi 
fere obsoletis diversa: P. tabuensi quoad colores affinis, sed cauda brevi primo visu 
distinguenda. 
Hab. James Island (Darwin); Indefatigable Island (Hade/). 
A specimen in Dr. Habel’s collection has no spots on the wings and lower back, but 
does not otherwise differ from the rest of his examples. These spots are somewhat 
variable, being well defined in some, obsolete in others, and entirely wanting in a few. 
Tn none, however, are they so well developed as in P. jamaicensis, the nearest ally to 
the present bird. 
“T found this bird only amongst low bushes which sometimes formed the under- 
growth of taller trees, in the swampy ground formed by the spring-tide floods in the 
lower parts of the islands. It has rather a dismal note, like other members of the 
family. In all the males I examined I observed that the left testicle was grey, while 
the right one was yellow. All my specimens were collected on Indefatigable Island. I 
did not meet with it on either Abingdon or Bindloe, where there are no swamps suitable 
for it.” —H. 
Genus ANGIALITIS. 
A world-wide genus of Plovers. ‘The species mentioned below is found nearly every- 
where in both North and South America. 
ZEGIALITIS SEMIPALMATA. 
Charadrius semipalmatus, Bp. Journ. Ac. Se. Phil. v. p. 98 (1825). 
Aigialitis semipalmata, Baird, Birds N. Am. p. 694; Scl. & Salv. P. Z.S. 1870, p. 323. 
Hiaticula semipalmata, G. R. Gray, Zool. Voy. Beagle, iii. p. 128. 
Hab. Galapagos (Darwin); Indefatigable Island (Hade/), 
“This Plover frequents the sandy beach or the shallow depressions of inland lagoons. 
On the beach it watches each receding wave, and after its retreat it thrusts its bill into 
the little holes in the sand, out of which water bubbles, to seize the crustacean hidden 
therein. It is not so shy as some other wading birds found in these islands; still it is 
not so tame as to be approached closely. In flying it utters some shrill note of alarm. 
Its eyelids are of a dark yellow colour”—Z. 
Genus H&MATOPUS. 
Another universally distributed genus, H. palliatus being common throughout the 
shores of the two continents of America.
