630 MESSRS. SCLATER AND SALVIN [DcC. 10, 



in a Tiinidad collection, as alluded to in his Cat. Am. B. p. 44 

 (note). H. insularis of Leotaud (Ois. de Trin. p. 186) would appear 

 to be referable to this species, and not to H. insularis, Sclater, 

 although both of them probably occur in that island. 



25. Chlorospingus albitemporalis (Lafr.) ; Sclater, Cat. 

 A. B. p. 89. 



The Venezuelan skin agrees with a Bolivian skin in Sclater's Col- 

 lection, and with a specimen from Costa Kica collected by Arce {cf. 

 Lawrence, Ann. L. N. Y. ix. p. 101). It may be true, as Dr. Ca- 

 banis has remarked (J. f. O. 1866, p. 162), that Lafresnaye's de- 

 scription of Taehyphonus albifempora includes the Mexican C. oph- 

 thalmicus and the present species. But Lafresnaye gives the habitat 

 of his bird as " Columbie ; " so that it seems quite fair to restrict 

 his term to the southern species, which is readily distinguishable from 

 the northern form by its small postocular spot, and the brighter 

 yellow of its breast and sides. 



We have carefully compared a series of Mexican and Guatemalan 

 specimens of C. ophthalmicus, but cannot find differences sufficiently 

 constant to distinguish them. Even if this were the case, Bona- 

 parte's term olivaceiis (which was founded on a Central-American 

 specimen*) would supersede Dr. Cabanis's proposed new name 

 postoculaj'is. 



30. SCLERURUS ALBIGULARIS. 



A single skin of a species most nearly resembling S. umbretta, but 

 apparently distinguishable by its white throat, smaller size, greyish 

 alDdomen, and brighter rufous crissum. It is probably S. albigularis 

 of Swainson's ' Birds of Brazil,' pi. 78, which figure we have never yet 

 succeeded in meeting with. See our remarks, P. Z. S. 1867, p. 574. 



34. SiTTASOMUs OLivACETJS, Max. Beitr. iii. p. 1146. 



After comparing a large number of specimens of this genus 

 together from various parts of America, we have come to the con- 

 clusion that there are only two good species, besides S. stictolamus 

 of Pelzeln (which we are not acquainted with). These are : — 1. S. 

 erythacus (Licht.), from Southern Brazil; and, 2. S. olivaceus 

 (Max.), which ranges from Southern Brazil into Southern Mexico. 

 The latter, according to this view, includes S. amazonus of Ama- 

 zonia, S. (/7-iseus of Tobago, and S. sylvioides of Southern Mexico 

 and Central America. These two species are very easily distin- 

 guishable, S. erythacus being of an ochreous colour beneath, very 

 different from S. olivaceus. 



AA. Grallarictjla loricata, Sclater, P. Z. S. 1858, p. 284. 

 Grallaria loricata, Scl. P. Z. S. 1857, p. 129. 

 A single skin of this species, originally described by Sclater from 

 Levraud's specimens in the Paris Museum.
