latter it has in common with the species of Chaunograptus here also 

 described. 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, the}' 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

 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.

 As the original description of the genus has to be regarded that of the 

 genotype, C. calicularis, 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 

 typical Graptolites, in having been apparently tree and oceanic, and in the 

 possession of a corneous or subcalcareous test or polypary."
