298 PROCEEDINGS OP THE ACADEMY OP 



examination of others of the collection made will result in the detection of ad- 

 ditional ones. 



I defer for the present any notice of the habits and peculiarities of these and 

 other birds of the Cape, preferring to make this the subject of a special memoir, 

 after a longer residence shall have enabled me to collect all the facts bearing 

 on this subject. 



Picus lucasanus, Xantus. 



General appearance that of Picus nuttalli and scalaris. Bill stout : as long as 

 or longer than the head. Above black, banded transversely with white on the 

 back and scapulars to the nape, the rump and outer tail feathers entirely black, 

 quills with a row of white spots on each web : the outer square, the inner 

 rounded, these spots on the tertials becoming transversely quadrangular. Be- 

 neath brownish white, with rounded black spots on 'the sides of the breast, 

 passing behind on the flanks and under tail coverts into transverse bars. 

 Greater inner wing coverts transversely barred. Outer two tail feathers white, 

 with one, sometimes two terminal bars, next to which are one or two bars on 

 the inner web only ; third feather black, the outer web mostly white, with traces 

 of a terminal black bar : sometimes there is a greater predominance of black 

 on the inner web. Two white stripes on side of head, one starting above, the 

 other below the eye with a tendency to meet behind and form a whitish collar 

 on the nape. Male with the entire top of the head streaked with red, becom- 

 ing more conspicuous behind ; each red streak with a white spot at base. 

 Feathers covering the nostrils smoky brown. 



Length 7-15, extent 12-15, wing 4-00, bill above 1-00, middle toe and claw 

 80. 



Campylorhynchcs affinis, Xantus. 



Very similar to C. brunneicapillus. Above grayish olive, each feather on the 

 back streaked with white, bordered externally by black. Upper tail coverts 

 and upper surface of tail grayish, with indistinct transverse black bars, much 

 broken ; quills with a marginal row of rounded whitish spots on each web. 

 Beneath white, sometimes very faintly tinged behind with yellowish brown ; 

 the whole under surface quite uniformly marked with rounded spots (more 

 elongated anteriorly) and of much the same size. On the breast these spots are 

 rather angular and generally do not cross both webs ; posteriorly, however, they 

 are more central, and several are sometimes strung along the shaft of the feather. 

 These spots are larger and rounder on the under tail coverts. Tail feathers, 

 excepting the two central black, each web banded from the base with alter- 

 nating bars of white, six or more in each series. Top of the head uniform cin- 

 namon brown, perhaps slightly paler towards the edges of the feathers ; a white 

 line from the nostrils over the eye to the nape, the white, however, streaked 

 with black. Bill and legs dark brown, base of under mandible paler. 



Length 7-50, extent 9-75, wing 4-35, tail 4-40, bill above -90, tarsus 1-10. 



Harporhynchus cinereds, Xantus. 



Very similar to Mimus montanus, with longer and more curved bill. The up- 

 per parts are grayish brown or cinereous with a faint trace of rufous on the 

 rump. Beneath white with a tinge of brownish yellowish towards the vent ; 

 the breast and sides with sharply defined sagittate or subtriangular spots of 

 brown, scarcely elongated on the sides, the shade of brown similar to, but 

 darker than that of the back. The lateral tail feathers are tipped with white, 

 the outer one sometimes edged with the same. There are two narrow dull 

 whitish bands on the wings. 



Length about 10 inches, wing 4-00, tail 4-75, bill above (in a straight line) 

 1-00. 



This species is very abundant at the Cape, and its nests are found among the 

 cactuses in large numbers. The eggs resemble those of the mocking birds 

 much more than those of the rest of the genus.
