There is a strong possibility that it belongs to another class of the animal kingdom and its similarity to certain bryozoans such as e. g. Vinella might suggest its bryozoan affinities. Still we are not aware of any genus of fossil bryozoans with which it actually could be united. The reference to Chaunograptus is wholly tentative and based on the creeping, attached mode of existence and irregular branching. While Chaunograptus shows a clear composition of the branches of distinct thecae, they appear in this form as continuous tubes ; but it must be conceded that the branches are too thin and the preservation is not quite good enough to permit a conclusive observation in regard to this and other points. It is Fig. i„ chTunograptus ? e. g. quite possible or even probable that the numer- rectilinea sp. nov. Enlargement ; .

Their approximately uniform length and slight widening in distal direction are quite suggestive of such an explanation. On the other hand, from its general aspect alone one would feel inclined to bring this species under Mastigograptus as we have noted before and the appearance of the apertures as simple pores would support this reference. corynoides Nicholson. 1867 As the original description of the genus has to be regarded that of the genotype, C . c a 1 i c u 1 a r i s, which concludes with the following short diagnosis : " Corynoides forms a hollow tube, probably corneous, provided with a single or double radicle or mucro, and developed distally into a cuplike ' hydrotheca.' Unlike the Graptolitidae proper, Corynoides has evidently been composed of a single polypite only, though it resembles the
