This is by far the best known species of Xesomimus. It is known from 

 Indefatigable, Jervis, and James Islands. Mr. Harris' part}' also found it fre- 

 qnently on Wenman, one of the two small detached northern islands. This is one 

 of the most peculiar phenomena in the distribution of the Galapagos birds ; but we 

 may state that we have most carefully compared our five series, and do not find any 

 constant character at all to distinguish the Wenman birds from those of Jervis, 

 James, and Indefatigable. 



Another interesting fact is that no Xesomimus was found on Duncan Island, 

 although diligently songht for. We have a large series from all the four islands. 



6. Nesomimus melanotis carringtoni W. Rothsch. 



-V. curringtum W. Rothsch. ia Bull. B. 0. Club (October) (1898).* 



Very closely allied to X. melanotis melanotis, but distinguishable by a longer 

 and slenderer bill, shorter wing and generally paler upper surface. Wing shorter, 

 and tips to rectrices larger than in ^V. bauri. Wing S 1U8 — 111 mm., ? 1911 — 

 104 mm., tail 6 110 — 115, ? approximately 105 (all worn), exposed culmen cJ about 

 28 mm., ¥ about ^0 mm. " Iris yellowisli." 



Former collectors did not mention a Nesomimus on Barringtou Island ; Messrs. 

 Baur & Adams, however, say that they procured specimens there, but they were 

 lost. The new collections contain a good series of this form. 



Eight specimens in Tring Museum, including the type. 



The name of this form has unfortunately been misprinted, as it should of course 

 have been sjjelt with a b. 



7. Nesomimus melanotis huUi W. Rothsch. 



N. huUi, W. Rothschild in Bull. B. 0. Club. p. 52 (May 1898). 



Differs from S. melanotis melanotis in having the buffy-white tips to the 

 primaries — and still more those to the secondaries — decidedly wider, and in having 

 a very distinct monstache-like line of black spots from the base of tlie mandible to 

 the neck. Dimensions as in ^V. 7nelanotis melanotis. 



This form was found abundantly on Culpepper Island. It is named as a 

 compliment to Mr. Hull, one of the collectors of the expedition. 



Six specimens in Tring Museum, including the type. 



8. Nesomimus melanotis bauri Ridgw. 



N. bniiri, Ridgway in Proc. U.S. Nd. .l/ii-?. XVII. p. 367 (1H'J4). XIX. p. 492(189fi). 



Differs from X. melanotis melanotis in having a longer bill, lighter sides of 

 breast and body, smaller white terminal spots to the rectrices, and in having a 

 monstache-like line of blackish spots along the sides of the throat. It differs from 

 X. melatiotis personatus of Abingdon Island in being much lighter above, the colour 



• Nesomimus harringtonensis nom. nud. Baur, in Amer. lYaiuralist, 1897, on list between pages 780 

 and 781, without description, must be added as a probable synonym. The specimen obtained was really 

 lost at Guayaquil.
