in a fossil state in the palzeozoic rocks. My reason for assigning such 
a position to the Graptolites, is the discovery I have made in eine 
upon the coral banks of Key- West, of a new genus of Bryozoa, in whic 
the arrangement of the cells resembles that of the Graptolites il 
more than either Virgularia and Sertularia, and the delicate stem 
which, if fossilized, are pena have left an impression very simi- 
lar to that of most Graptolites. I have not yet had an opportunity of 
publishing my investigations upon this singular creature ; but | have no 
oubt left in my mind that it is a living representative of the fossil 
Graniclien, for which [ propose the name of Cladobryus hyalinus, as 
it differs from most of the ordinary Bryozoa, by the regular branehing 
of its stem, and resembles, 1 in that respect strikingly, the new genus 
Cladograpsus of Geinitz. 1 have collected a sufficient supply of this 
remarkable animal, in alcohol, to provide all the paleontologists with 
it. To trace the true yoo of the Graptolites, the genera Crisia, 
and Eucratea, ought to be c ared. Upon this interesting —
