Xiphorhynchus guttatoides (Lafresnaye). The form guttatoides of Colombia, is a subspecies of Xiphorhynchus guttatus Lichtenstein, of which the race inhabiting Br. Guiana is X. g. sororius (Berlepsch and Hartert), type locality Perico, Orinoco River. Berlepsch and Hartert (Nov. Zool., 1902, ix, p. 63), who originally described this form as Dendrornis rostripallens sororia, mention a specimen from Quonja, Br. Guiana, coll. Whitely, agreeing with birds from Perico. Schomburgk (l. c., p. 690, sub nom. Dendrocolaptes guttatus) says he found it throughout Br. Guiana; Salvin (l. c., 1885, p. 422), referring to it as Dendrornis guttatoides, records a specimen from Bartica Grove; and Dawson (l. c., p. 29) lists it under the same name. Quelch (Animal Life in Br. Guiana, 1901, p. 177), speaking of Dendrornis pardalotus and Dendrornis guttatoides, says that one or both of these species will invariably be found in collections made in the forest districts.
Elænia guianensis Berlepsch.—The type locality of this species is Camacusa, British Guiana. It has been recorded by Salvin (l. c., 1885, p. 295) as Elainea elegans, from Bartica Grove, Camacusa, etc.; by Sclater (Cat. Birds Br. Mus., 1888, xiv, p. 150) as Elainea gaimardi, from Roraima; and by Dawson (l. c., p. 13) as Myiopagis gaimardi. The Br. Guiana form now stands, Myiopagis gaimardii guianensis (Berlepsch).
Empidochanes fuscatus cabanisi Léotaud. —Recorded by Salvin (l. c., 1885, p. 297, sub nom. Empidochanes olivus) from Bartica Grove; and by Sclater (Cat. Birds Br. Mus., 1888, xiv, p. 224, sub nom. Empidonax oliva), who states that this is the northern form of E. bimaculatus (d’Orb. and Lafr.), adding that he was doubtful whether it was really entitled to the name oliva. The type locality of cabanisi is Trinidad. The form inhabiting Cayenne is Empidochanes fuscatus fumosus Berlepsch, to which we suppose the Surinam bird also belongs.
Riparia riparia (Linné). -Recorded by Salvin (l. c., 1885, p. 206) as Cotile riparia, from Bartica Grove.
Sporophila bouvronides (Lesson). —Brabourne and Chubb (Birds of South America, 1912, i, p. 367) refer S. ocellata (Scl. and Salv.) to this species, and give the type locality Trinidad. References to S. ocellata in Guiana probably apply to the same bird which Mr. Beebe had in hand. Mr. Beebe also lists S. lineola (Linn.). Sharpe (Cat. Birds Br. Mus., 1888, xii, p. 130) lists S. ocellata from Carimang River, Br. Guiana. Dawson (l. c., p. 48) mentions both ocellata and lineola.
Thraupis palmarum palmarum (Wied). Schomburgk (l. c., p. 670, sub nom. Tanagra olivascens) states that it is abundant at the coast. It has been recorded by Salvin (l. c., 1885, p. 210) from Bartica Grove and Roraima; by Quelch (Timehri, 1891, p. 81; Reprint, p. 13) who says it is common in Georgetown, mentioning the species again later (Animal Life in Br. Guiana, 1901, p. 113); by Price (Timehri, 1891, p. 63) who describes the eggs; by Percival (l. c., p. 16) who states that it is “not very often seen in the Gardens, though common among the innumerable cocoanut palms in and about town,” where the writer also has seen it; and by Dawson (l. c., p. 46; and Timehri, 1911, p. 272). The type locality of palmarum is Bahia, and judging from material examined, I would say that birds from Cayenne, Surinam, and Br. Guiana, differ distinctly from true palmarum, and are more nearly allied to, if not indistinguishable from, the Eastern Peruvian race, Thraupis palmarum melanoptera (Sclater).
Saucerottia erythronota (Lesson). —With reference to this species also marked with a star, we do not find in Mr. Beebe’s list Agyrtrina fimbriata fimbriata (Gmelin), which is common in Br. Guiana, and which has been recorded from Bartica by Chubb (l. c., p. 395). This bird has sometimes been confused with Saucerottia erythronota (Cf. Salvin, Cat. Birds Br. Mus., 1892, xvi, p. 187) and has been listed from Bartica by Salvin (Ibis, 1885, p. 435) under the name Agyrtrina tobaci of which erythronota, type locality Trinidad, is a subspecies.
A longer stay at Bartica, no doubt would have augmented Mr. Beebe’s list considerably. For instance, Mr. Chubb, in his work on the birds of British Guiana, records twenty-seven species in the McConnell Collection, which are not included in Mr. Beebe’s list.
In Chapter XIII we find an account of the author’s ornithological discoveries, pertaining mostly to nests and eggs, with excellent photographic illustrations. Some of these discoveries, however, are by no means entirely new, reliable information on nests and eggs having been published in regard to at least twelve of the seventeen species discussed. Attention is called to the following records:
Chæmepelia talpacoti (Temminck and Knip). —Dalgleish (Proc. Roy. Phys. Soc. Edinburgh, 1889, x, p. 86) describes two nests, each containing two eggs, found Nov. 20, 1886, in Paraguay. Nehrkorn (Kat. Eiersamm, 1899, p. 184) lists eggs from Paraguay, 23 × 18 mm. Euler (Rev. Mus. Paulista, 1900, iv, p. 98) describes nests and eggs, 22.5 × 18 mm. Ihering (Rev. Mus. Paulista, 1900, iv, p. 282) describes nest and eggs, and says that he found a nest built upon the deserted nest of another bird, containing two eggs, 22 × 17 mm. F. P. and A. P. Penard (l. c., 1908, i, p. 340) describe habits, nests, and eggs under C. rufipennis, assuming talpacoti and rufipennis identical in Surinam, judging from specimens which had been identified for them in England as rufipennis. Apparently there is some confusion here, and the bird identified as rufipennis was probably the newly described Chæmepelia arthuri Bangs and Penard, (Bull. M. C. Z. 1917, p. 45).
