On new species of Birds from the Rio Napo, in the Republic of 

 Ecuador. By Philip Lutley Slater, M.A. 



El^enia luteiventris. 



Supra fusca unicolor, alis caudaque paulo saturatioribus ; gut- 

 ture griseo, abdomine medio et crisso cum tectricibus alarum 

 inferioribus sulphur eo-fiavis, pectore et lateribus oleagineis ; 

 rostro et pedibus nigris. 

 Long, tota 5*3, alae 2*8, caudse 2*3, tarsi 0*6. 

 A typical Elcenia of the same form as E. pagana, the type of the 

 genus, but of smaller size, and differing in colouring from all mem- 

 bers of the group with which I am acquainted. 



Cretjrgops*, genus novum, Lanioni et Trichothraupidi affine, sed 

 rostro diverso. Rostrum breve, crassum, culmine versus apicem 

 incurvOy gonyde vix ascendente, commissura modice arcuata, 

 mandibula superiore dente mediali distincto et altero finali 

 instructo ; vibrissis rictalibus nonnullis : alee modicte, caudm 

 tertiam partem attingentes, remigibus secunda, quarta et quinta 

 cequalibus et longissimis, prima his paulo breviore : cauda 

 long a, apice quadrat a. 



Cretjrgops verticalis, J. Verreaux, MS. 



Supra fuscescenti-schistacea, pileo semicristato saturate ferru- 

 gineo, hujus lateribus cumfronte nigricantibus : alis caudaque 

 fusco-nigris ; subtus ferruginescenti-ochracea : rostro nigri- 

 cante, gonydis basi albida, pedibus fuscis. 

 Long, tota 6*2, alse 3 - 2, caudse 2 5, rostri a rictu 0*7, tarsi 0*85 . 

 This peculiar Tanager seems to belong to the neighbourhood of 

 Lanio, Tachyphonus and their allies, and, like the former, has a very 

 sharply defined notch about two-thirds of the distance along the edge 

 of the upper mandible. But the bill is otherwise very different from 

 that of Lanio, being much shorter, broader, thicker, and more swollen, 

 with the culmen much arched towards the tip. The single specimen 

 which I have examined is not in very good condition, but its perfect 

 distinctness from every known species of Tanager is obvious at first 

 sight.— Proc. Zool. Soc. Jan. 26, 1858. 



On the Genera Orbulina and Globigerina of D" Orbigny . 

 By L. F. Pourtales. 



Hitherto the two genera of Foraminifera established under the 

 names of Orbulina and Globigerina by D'Orbigny had been widely 

 separated in the classification ; he had even put them in different 

 orders, although he had remarked the similarity in the structure of 

 the shell. Ehrenberg also places them in different families (the 

 former under the name of Miliola), but marks the two genera of 

 Miliola and Gromia as doubtful, and appends to the characteristics
