106 DR. BAIRD ON NEW SPECIES OF WORMS. [April 21, 



12. Dryoscopus hamatxjs, n. sp. Supra niger, nitore nonnullo 

 chalybeo; uropygii plumis longis, sericeis, albis ; subtus albus ; 

 subalaribus et subcaudalibus albis ; tectricibus alarum et re- 

 migibus, primo et secundo exceptis, albo limbatis ; rostro gra- 

 cili, valde compresso, maxillce apice uncinato, nigro ; pedibus 

 nigris. 



Long, circa 5" 10'", rostr. a fr. 8'", al. 3", caud. 2|", tars. 10'". 



13. ESTRELDA PHCENICOTIS, Sw. 



14. EsTRELDA MINIMA, Vieill. (mutilated skin, the head wanting). 



15. Spermestes cucullata, Sw. 



16. euplectes flaviceps, sw. 



17. Vidua paradisea (L.). 



18. Vidua macroura (Gm.). 



19. Vidua euues, n. sp. (PI. XV.) Minor, nigra; macula 

 scapulari majuscula, rufo-cinnamomea ; subtus late nigro-mar- 

 ginata ; margine axillari Jiavo-rufescente ; subalaribus albis; 

 remigibus omnibus bast niveis, speculum alarem formantibus ; 

 rostro margaritaceo, basi supra et infra plumbeo ; pedibus

This fine and apparently undescribed species belongs to the divi- 

 sion Urobrachya. It is one of the smallest of the whole group, and 

 appears to be nearly related to the XJ. albonotata of Cassin, which, 

 however, has the scapular spot of a pure rich yellow. 



20. TrERON NUDIROSTRIS (Sw.). 



21. CoLUMBA guinea, Liuu. 



22. Dendrocygna viduata (Linn.). 



2. Descriptions of several New Species of Worms belong- 

 ing TO THE Annelida erkantia and sedentaria or tu- 

 bicola of Milne-Edwards. By W. Baird, M.D., F.L.S. 



The following very interesting species of Annelides were collected 

 hy Mr. Lord, during the time he was engaged as naturalist on the 

 N.W. American Boundary Commission. They appear to me to be 

 undescribed. They will be figured in the forthcoming report of the 

 labours of the commission. 



1. Lepidonotus insignis, Baird. 



This is a very fine species of the genus Lepidonotus. It is rather 

 more than 3 inches long, and is nearly | an inch in breadth, exclu-
