The author describes the following species of l^-ilobites; 



Agnostits sf>itiensis n. sp. 



There are considerable affinities between this species and .-/. nfadicus Hartt, also 

 with A. montis Matthew. 



Microdiscus: The author uses A/, pu/iclatus Salter for the type of the genus and not 

 M. qiuiJr'icostatns Flmmons, certainly the young of the Trinucleus from the Hudson 

 River group; and remarks, "Sliould I'empliigaspis hullata Hall, prove to belong to this 

 genus, this name will have to be adopted as Emmons founded his genus Microdiscus 

 on a young of another genus." 



Matthew Trans. N. Y. Acad. Sci., 1896, p. 236, remarks, as a general rule, in the 

 genus Microdiscus the number of rings in the axis of the pygidium increase according 

 to the geological age of the species. The majority of those of the Olenellus zone have 

 but few rings (4 to 6), but in the Paradoxides zone species \vith many rings (S to 10, 

 even 12) are multiplied. 



He divides the genus into four Sections: With long glabella — Section 1, Lobatus; 

 Section 2, Speciosus. With short glabella — Section 3, Dawsonia ; Section 4, Eodiscus. 



The following Himalayan species are described and illustrated: 



Microdiscus Griesbachi sp. nov. T!ie species agrees in general characters with .1/. 

 connexits Walcott, M. Ini'iinantcnsis sp. nu\'. RcdluliKi Noetl'ingi Redlich. 



The author remarks that this species is very closely related to R. nohilis Walcott. 

 Indeed, it seems difficult to separate the new Chinese species R. cli'inensis Walcott, R. 

 finalis Walcott and R. nohilis Walcott, by any strongly marked and constant features 

 from the Indian species.

Under the genus Ptychoparia, Corda, 1S47, the author remarks: 



There has been extraordinary diversity in the use of the generic name Ptychoparia, 

 and in spite of the recent efforts of paleontologists to bring order out of chaos it can- 

 not be said that uniformity of usage prevails at the present date.
