94. Nelson on a new Cliff-Swallow. 



[A new Subspecies of the Cuban Cliff-Swallow. By E. W. Nelson. 

 Proc. Biol. Soc. Washington, xv. p. 211 (1902).] 



A new subspecies of Cliff-Swallow is described as Petro- 

 chelidon fulva pallida. It is based on specimens obtained 

 by the Biological Survey in Coahuila, Mexico, and its dis- 

 tribution is given as the "arid border of the tableland in 

 N.E. Mexico." 



95. North on the Egg of the Kagu. 



[Description of the Eggs of the Kagu, Rhinoehetus jubatus Verreaux 

 et Des Murs. By Alfred J. North, C.M.Z.S. Records Austral. Mus. 

 iv. pp. 310, 311, pi. 1.] 



Mr. North describes and. figures eggs of the Kagu of New 

 Caledonia {Rhinoehetus jubatus) laid in confinement at 

 Sydney. He points out their resemblance to those of some 

 of the Laridae, but they are likewise to be compared with 

 those of some of the Cranes (Gruidse), to which family the 

 Kagu is usually supposed to be allied. 



The egg of this bird has already been described and figured 

 by Bartlett from an example laid in the Zoological Society's 

 Gardens (see P. Z. S. 1868, p. 154, pi. xii. fig. 3). 



96. Oberholser on Birds from Paraguay. 



[List of Birds collected by William T. Foster in Paraguay. By Harry 

 C. Oberholser. Proc. U.S. Nat. Mus. xxv. pp. 127-147 (1902).] 



A collection of birds made by Mr. W. T. Foster at Sapucay, 

 in Paraguay, which is a short distance to the east of Asuncion, 

 contains 78 specimens, which are referred to 65 species and 

 subspecies. Mr. Oberholser has already published descrip- 

 tions of the new forms (Proc. Biol. Soc. Washington, xix. 

 p. 187). He now gives a complete list of the species with 

 critical notes, and proposes to alter the nomenclature 

 according to the American system. The most noticeable 

 novelty appears to be a new Arremon (A. callistus). allied to 

 A. polionotus. But it is based on a single specimen only, 

 and appears to be a little doubtful.
