62 SMITHSONIAN MISCELLANEOUS COLLECTIONS [voL. 48 
is rendered untenable because of Nanodes Schonherr,' a genus of 
Coleoptera. Some time ago Forbes proposed to put Lathamus 
Lesson in place of Nanodes Vigors and Horsfield, dating the former 
from 1831,° and considering its type to be Lathamus rubrifrons 
Lesson (= Psittacus discolor Shaw); but the earlier use of La- 
thamus, also by Lesson, as a subgenus of Psittacus, for Psittacus, 
aurifrons Lesson,’ makes it a synonym of Bolborhynchus and thus 
unavailable for Nanodes. ‘The next and only other synonym of 
Nanodes, Euphema Wagler,’ becomes consequently its tenable title, 
since this is not invalidated by Euphemus Rafinesque,? a nomen 
nudum. 
The type and sole species ought therefore to be called: 
Euphema discolor (Shaw). 
DENDRORNIS Eyton 
The name of the group of Dendrocolaptidz to which the generic 
term Dendrornis Eyton’ has been applied must apparently be 
changed. The type of Xiphorhynchus Swainson as usually cited® is 
Dendrocolaptes procurvus Temminck; but earlier in the same year 
Swainson had used this generic name in describing Xiphorhynchus 
flavigaster,? which is a member of the present genus Dendrornis. 
Although Swainson evidently intended to make Dendrocolaptes pro- 
curvus Temminck the type of Xiphorhynchus, he defeated his pur- 
pose by allowing the previous publication of Xiphorhynchus in com- 
bination with the name of a species of another group, such publica- 
tion being quite sufficient to fix the name of a genus. Since in this 
case the question is not complicated by the mention of any other 
species, Xiphorhynchus flavigaster Swainso * must be considered the 
type of Xiphorhynchus, and this generic term therefore transferred 
to displace Dendrornis. 
The species are as follows: 
Xiphorhynchus guttatus. (Lichtenstein). 
Xiphorhynchus guttatoides (Lafresnaye).
