Z. Cowleyi, sp. nov. Hicheaber antennis palpis pedibusque 
(femoribus ad basin exceptis) infuscatis; minus nitida ; 
‘capite valde elongato antice anguste rostriformi (labro quam 
latiori multo longiori), sparsius subfortiter punctulato, inter 
oculos longitudinaliter canaliculato; palpis maxillaribus 
valde elongatis (quam antennarum articuli basales 3 con- 
juncti vix brevioribus), articulo apicali gracili apicem versus 
parum incrassato ; antennis exempli typici fractis, articulo 
2° quam 1" vix breviori ; oculis permagnis, supra et subtus 
subcontiguis; prothorace quam (ad basin) latiori parum 
longiori, a basi ad apicem arcuatim angustato supra sat 
equali, fere ut caput punctulato sed paullo magis crebre ; 
elytris breviter pubescentibus confertim subtiliter punctula- 
tis, lineis elevatis haud instructis. Long., 631.; lat., 131. 
The head of this species is so peculiar as to suggest a question 
whether it might not be regarded as generically distinct from 
Zonitis, but most of the characters seem to be only exaggerations 
of what is to be found in other species of the genus. The head 
is not much longer (though it is narrower and more rostriform in 
front) than that of Z. rostrata, Blessig. The eyes are much 
larger than in any other Zonitis that I have seen, and the 
maxillary palpi much longer than in any other except longipalpis
