Eight species of Brachiopoda inhabit the Egean, seven of which are Tere- 
bratule and one a Crania. They range from 25 to 230 fathoms, but abound 
between 70 and 100 on a bottom of nullipore and coral, where the number of 
individuals belonging to this tribe taken in a single dredge usually far ex- 
ceeds that of all the other Testacea accompanying them. Their presence and 
abundance is an unfailing clue to the region from whence the produce of the 
dredge has been obtained. They are gregarious, living on clean ground, and 
were found only in a dead state in the neighbouring mud. Of the largest species, 
the Terebratula vitrea, two broken specimens only were taken, one of them 
at the great depth of 1380 feet below the surface. No living examples of 
any of the species, however, were found below 105 fathoms. The uniform 
muddy bottom below that depth is unfavourable to their presence. The same 
remarks apply to Crania ringens. It is remarkable that Terebratula caput 
serpentis, which is not uncommon in the western Mediterranean, is altogether 
absent in the eastern. Thecidia, also, was never met with in the latter.
