OF TKE GALAPAGOS AECHIPELAGO. 501 



c? (Indefatigable Island) nigricanti-cinereus, fere unicolor, dorso et alis extus rufes- 

 cente oleagineo perfusis, hypochondriis imis et tectricibus caudse 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, alae 2'6, caudae I'O, 

 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 {Habel). 



A specimen in Dr. Habel's collection has no spots on the wings and lower back, but 

 does not otherwise diiFer from the rest of his examples. These spots are somewhat 

 variable, being well deiined in some, obsolete in others, and entirely wanting in a few. 

 In none, however, are they so well developed as in P. jamaicensis, the nearest ally to 

 the present bird. 



"I 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, whUe 

 the right one was yellow. All my specimens were collected on Indefatigable Island. I 

 did not meet vdth it on either Abingdon or Bindloe, where there are no swamps suitable 

 for it."— ^. 



Genus ^gialitis. 



A world-wide genus of Plovers. The species mentioned below is found nearly every- 

 where in both North and South America.

Hob. Galapagos [Darwin) ; Indefatigable Island (Habel), 



" 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 biU 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" — H. 



Genus BLematopus. 

 Another universally distributed genus, If. palliatm being common throughout the 

 shores of the two continents of America.
