BANGS AND PENARD: SURINAM BIRDS. 71 



196. Lathria cinerea cinerea (Vieillot). 



Fifteen specimens, both sexes, Vicinity of Paramaribo, Lelydorp, 

 Javaweg, and Rijsdijkweg, February, March, April, May, June, and 

 August. 



Berlepsch and Hartert (Nov. zool., 1902, 9, p. 57) state that "there 

 is no difference between Bahia specimens (plumhea) and Guiana birds 

 (cinerea)." But in all specimens seen by us, the bird ranging from 

 Bahia to Bolivia is larger and paler colored than the Guiana form. 

 The largest specimen examined is from San Mateo, Bolivia (wing, 

 130). Wing-measurements of Bahia birds vary from 124 to 127, 

 and of Guiana birds from 116 to 123. 



We do not hesitate to recognize two races; a northern, Lathria 

 cinerea cinerea Vieill., type-locality, Cayenne, and a southern, Lathria 

 cinerea plumhea Licht., type-locality, Bahia. 



197. LiPAUGUS SIMPLEX FREDERICI, SUbsp. nOV. 



Type.— M. C. Z. 80,922, (921 Penard Coll.). Adult &. Vicinity 

 of Paramaribo, Surinam, 6 June, 1913, E. Graanoogst. 



Named in honor of Frederik P. Penard, co-author of De vogels van 

 Guyana. 



Characters. — Similar to Lipaugus simpler simplex (Licht.) of Bahia, 

 but darker throughout, the color of the upper parts and breast much 

 grayer and less olivaceous; wings and ti^il darker, more blackish and 

 less brownish; belly slightly darker, grayer and less yellowish; tail 

 slightly shorter. 



Measurements. — Type, adult cf ; wing, 99; tail, 85; tarsus, 22.5; 

 exposed culmen 19.5. 



Remarks.— This subspecies has been much discussed, its characters 

 having been pointed out by Berlepsch and Hartert (Nov. zool., 1902, 

 9, p. 57) who call it Lipaugus simplex immundus Scl. & Salv. Hell- 

 mayr (Nov. zool., 1905, 12, p. 295) states that L. immundus of Cayenne 

 is really an entirely different bird, not even belonging in the geniis 

 Lipaugus. The range of this form apparently extends from Venezuela 

 and the Orinoco region to the Lower Amazon. 



198. Attila thamnophiloides Spix. 



Seven specimens, both sexes. Vicinity of Paramaribo, and Javaweg, 

 April, May, and December.
