seen three or fonr times near Tagns Cove, on Allipmarl<', but, being a sliy bird, 

 none were taken. At Tagus Cove a nest was seen in a busli, 5 ft. higli, that 1 took 

 to be that of a Cocojzus. It was a rnde strncture of twigs. Some broken eggshells 

 of a plain white colour, though probably bleached, were lying on the ground under 

 the nest." 



The call of this bird is a subdued vontriloqnial cu cu i-u. 



This bird is remarkable as being ajiparently (?) resident and breeding on the 

 Galapagos Islands, and nevertheless being (ai)parently) inseparable from tiie conti- 

 nental form. If it is really resident and breeding it would be the only land-bird 

 not peculiar to the group. All the Pas»-ies breeding on the group arc specially 

 differentiated Galajiagan forms, none being identical with those of the mainland. 

 Coccijzus melacorypliiis, however, is somewhat rare and apparently a recent 

 immigrant.

This excellentlv distinguished species is only known from Gaadeloape Island, 

 "about 29' N. lat., otf the coast of Lower California. It differs conspicuously from 

 its allies in the colour and markings of the rump, underside, and tail. Mr. Beck 

 obtained two adult females and six young birds of this very rare bird. It is 

 erroneous that this bird ever occurred in California, where P. cheriway alone occurs 

 (cf. Sharpe, Hand-list I p. --MS).]

This time Mr. Beck has sent many more uniform dark sooty blackish birds 

 than light ones. None of the dark birds show a trace of the light plumage. (See 

 our remarks, Nov. Zool. VII p. 174.) 



We have now received skins from Xarborongh, Indefatigable, and Seymour 

 Islands. 



A bird from Albemarle (Green coll.) shows rather light bars on the inner 

 secondaries, and very extended light bases on the head. These birds were not nesting 

 on any of the islands visited, though nests were fonnd on nearly all. On Seymour 

 and Daphne two large nests were seen, each being placed on the side of a steep 

 hill. That on Daphne was placed inside the crater well up on the side, but on 

 Seymour the nest was placed on the top of a bluff commanding quite an extensive 

 view. On Narborough a pair of birds were copulating, and a nest was found freshly 

 built and placed on the ground a hundred yards from a patch of mangroves. Large, 

 tall mangroves, dead and alive, were near by, that would have furnished excellent 

 sites for nests had the birds wished to nest in trees. On Albemarle, at Tagus Cove, 

 three nests were seen in trees, immense nests that had been added to year after 

 year. Two were about 5 ft. high and 4 ft. wide at base. They resembled nests of 

 Pdiiilion haliaefMS more than those of Buteo swainsoni as I have found them iu 

 California.
