428 DR. G. HARTLAUB ON NEW AFRICAN BIRDS. [May 9, 
Heptathyra aubryi, Cope, Proc. Acad. N.S. Philad. 1859, p. 296 ; 
Gray, P. Z.S. 1860, p. 315. 
Heptathyra frenata (partly), Gray, P. Z. S. 1864, p. 94. 
Hab. Gaboon. I have not seen this species. 
3. HEPTATHYRA FRENATA. 
Cyclanorbis frenata, Peters’s MS. 1848. 
Cyclanosteus frenatus, Peters’s MS. 1850; Gray, Cat. Shield 
Rept. B. M. 64, 1855. 
Cycloderma frenatum, Peters, Monatsbericht, 1854, p. 216. 
Aspidochelys livingstonii, Gray, P. Z. 8. 1860, p. 6, pl. xx11. ; 
ibid. p. 315. 
Heptathyra livingstonii, Gray, P. Z. 8. 1864, p. 94. 
H. frenata (partly), Gray, P. Z.S. 1864, p. 94. 
Hab. Central Africa ; River Zambesi (Peters, Mus. Berlin) ; 
(Livingstone, Mus. Brit.). 
These two species may be the same; they both have black marks 
on the head; but I have not been able to compare them. 
The difference in the form of the callosities (pointed out in my 
last paper) may depend on the age or the individual peculiarities of 
the two specimens figured. 
Dr. Sclater informs me that, judging from a cursory examination, 
the specimen in the Berlin Museum seemed exactly like that figured 
in the ‘ Proceedings.’
