330 Mr. R. I. Pocock on some 
them can stand as its type. It may be added, however, that 
carpophagus was eliminated by Meinert in 1869 (Nat. Tidskr. 
iv. p. 97) under the name sodalis as a Senipeus, of which it 
may be regarded as the type if Scnzpeus is ever restored to 
use. Thus two of the species upon which Geophilus was 
primarily based are accounted for, and neither can be recog- 
nized as its type according to the “elimination” system, 
What, then, becomes of the generic name? Since neither of 
the two just mentioned is available, it must fall upon either 
acuminatus or subterraneus, and to them it was applied by 
Newport in his classical monograph (Tr. Linn. Soc. xix. 
pp- 434-438, 1845). But acuminatus was removed by 
C. Koch under the name rosulans as Linotenia (Syst. Myr. 
S. 188, 1847). Hence subterraneus, being the last species 
left in the genus Geophilus, comes out as its type ; and since 
subterraneus is probably congeneric with gracilis, Meinert, 
the type of the genus Stégmatogaster of Latzel, Stigmatogaster 
becomes a synonym of Geophitlus. 
The four species, then, which originilly constituted the 
genus Geophilus must now be associated with the following 
generic names, whether or not the names take the rank that 
was primarily assigned to them :— 
Necrophlaophagus, Newport (= Arthronomalus, Newp.). 
Type longicornis, Leach. 
Scnipeus, Meinert. 
Type carpophagus, Leach (=sodalis, Mein.). 
Linotenta, Koch. 
Type acuminata, Leach (=rosulans, Koch). 
Geophilus, Leach (?= Stigmatogaster, Latz.). 
Type subterraneus, Leach. 
The adoption of the conclusions here stated involves two 
further changes in nomenclature, namely, the transference of 
the family name Geophilide to the group designated Himan- 
tariidee by Cook, and the introduction of a new name for the 
group which currently passes as Geophilide. Necrophloeo- 
phagide obviously suggests itself for this purpose, in spite of 
its polysyllables and cacophony. 
2. The Genera of Blaniuloid Diplopods. 
In 1836 (Bull. Soc. Philom. p. 72) Gervais established 
the genus Blaniulus for the reception of the blind Lulus guttu- 
latus (Bose), Fabricius, with which he rightly declared /ulus
