Schiodte and Meinert distinguished a new genus Glossobius 

 in 1883 from another new genus Eincflia and Dana's 

 Ceratothoa by the character that in GlossobiKs the fingers are 

 unequal, those of the third pair being the largest, whereas in 

 the other genera the fingers are equal or sub-equal. But in 

 this arrangement the only two species which Dana had 

 assigned to his Cerafothoa were transferred to Glossobius, so 

 that obviously Glossobius is a synonym of Ceralofhoa, Dana, 

 and the eleven species assigned by Schiodte and Meinert to 

 their Ccratofhoa, together with Ccnifofhoa dcplanata, Bovallius, 

 1885, will be properly grouped under the generic name 

 Meifiertia. The Cci'atothoa lineala of Miers, 1876, does not 

 appear to be noticed in the Danish Monograph. It was 

 founded on " a single specimen, probably young," which in the 

 opinion of the author himself " ought perhaps to be referred 

 to the genus Cyinothoa " ¥oy the present, therefore, it may be 

 left out of account.

Schiodte and Meinert divide the genus into three groups, 



respectively with the peraeon carinate, flattened or convex. 



The last group is sub-divided into those with the front angles 



of the first segment carinate, and those with the angles not
