PeiseiH'i'i liasstfongly objected to the inclusion of the ConularidEo 

 among the Pteropoda: the association of Con.iiJa/'iKSi witli littoral 

 foims like Trilobites and Spirifers of the Bokkeveld is contrary to 

 what one would expect in beds containing Pteropods. The sugges- 

 tion that the Comdarias were worms was not supported hy Nichol- 

 son's investigation into the minute structure of the shell. 



The ornamentation consists of very fine striations in the 

 younger forms, and then su Idenly becomes developed on a larger 

 scale; three periods sometimes can thus be distinguished in one 

 example. The very large ornamentation occurs on some impires- 

 sions of the outer shells, which are labelled C. pinchiniruut, Salter, 

 in manuscri])t, but I see no justification for separating this larger 

 form from the smaller ones ; the little pustules on the ribs are 

 hardly of specific significance. 



It is interesting to find the same species among so many other 

 South Afi'ican forms in Bolivia'.

Mr. Reed, in his descrijition of the Geological Commission's 

 specimens from the Bokkeveld beds, describes two sjjecies of 

 Rensselaeria, which he names K.sp. a. and M.kjj. I>. In the Albany 

 Museum there are three specimens which I think must be referable 

 to this genus, one, perhaps, is the same as R. Sjj. a. which has been 

 preserved under different ctmditioiis. the .second is cei-tainly 

 B. .yj. b., and the third, though (piite different from eithei- of the 

 others, may be a young form of 7'. sji. a.
