crinus ornatus; specimens of Hypanthocrinus decorus; Ichthyocrinus 

 Icevis ; two species of Stephanocrin[jSj and fragments of other 

 species, haTe been collected. Among the Brachiopoda, about 

 fifteen species have been added ; of a large part of which, there are 

 from ten to twenty specimens of each species. Among Trilobites,. 

 two specimens of Lichas {Platynotus) boltoni, several of Pkacops 

 limulurus, several of Calymene niagarensis, and one perfect speci- 

 men of Bumastis harriensis, have been added. When there are 

 duplicates, the best specimens have been selected for the Cabinet,, 

 and the others ren)ain packed, or in drawers, subject to further 

 direction. 



From the Pentamerus-galeatus limestone and Delthyris shaly 

 limestone, a considerable number ©f good specimens have been 

 added to the collection. These are diiefly of the Brachiopoda, of 

 the genera Lingular Lepteena, Orthisy. Delthyris and Atrypa. A 

 considerable number of Corals have likewise been added, but these 

 are almost entirely of undescribed species. The same remark will 

 apply to the greater part of all species from these rocks, and there- 

 fore no detailed catalogue of names can be given at the present 

 time. 



From the Onondaga-salt group, I have added several specimens 

 of a large fossil shell allied to the Megalodg!N, being the only fossil- 

 shell of this character yet known in owr Silurian beds. A new 

 species of Pentamerus, two of Murchisoni&j and one or two of 

 Pleurotomaria have been added from the same group. The oc 

 Gurrence of these fossils is very interesting, inasmuch as this group 

 is nearly destitute of fossils throughout the State, with the exception 

 of a single locality. 



A large number of specimens have been collected from the 

 Onondaga and Corniferous limestones. These are mostly of un- 

 described species ; and I have had no time to unpack the boxes, 

 and can only report them as ready for arrangement and description. 



A complete catalogue of the fossils and geological specimens of 

 the Medina sandstone, Clinton group, Niagara group and Onon- 

 daga Salt group, will be furnished to the Regents for the next 



Report.
