NEW YORK STATE MUSEUM 



a number of the specimens described by earlier authors as well as 

 of the many interesting specimens collected by the present officers 

 of the survey. The new study, from the present standpoint of 

 paleobotany, of our rich collection, some of which is representa- 

 tive, of the earliest known Lepidophytes, should throw new light 

 on the origin and nature of the primeval relatives of the modern 

 club moss order. The preparation of this paper has been much 

 delayed on account of pressure of other work in Mr White's charge, 

 but a large part of the preliminary and comparative work is already 

 done and the completed manuscript will probably be submitted be- 

 fore the close of the present winter. 



Devonic crinoids. In my last report I noted the fact that the 

 very interesting group constituting the Crinoidea occurring in the 

 Devonic rocks of this State had received such very scant study 

 that paleontologists are practically unfamiliar with their species. 

 Mr Edwin Kirk, who has undertaken the elaboration of this group 

 as represented by the fine material in the State Museum, has spent 

 such time as he has been able to command and the larger section of 

 the group, the camerate crinoids, has now been essentially revised 

 and completed. Publication of this work is deferred till the re- 

 vision of the other groups is complete, but it is already evident 

 that much of genuine interest and novelty to the science will be 

 set forth therein. 



Genera of the Paleozoic corals. Reference has before been made 

 to the fact that an extensive memoir on these important corals was 

 completed some years ago and a very large part of the necessary 

 illustration prepared. It has not seemed wise to submit this 

 memoir for publication until it can be revised by a student specially 

 expert in this group of organisms. It is hoped that it may be prac- 

 ticable in the course of the coming year to arrange for this revision 

 and thus make the work entirely creditable to the science. 



Paleontologic collections. The active field operations have 

 resulted in bringing into the Museum important acquisitions. 

 Among them is a series of cystids mostly of the genus Pleuro- 

 cystites, from the Trenton limestone at Glens Falls, and a collec- 

 tion of marine algae from the same rocks, belonging to the genera 

 Callithamnopsis and Chaetocladus, heretofore known only from the 

 Trenton of Wisconsin. At Saratoga lake the fauna of the Lor- 

 raine has been found to be extensively represented, including a 

 noteworthy species of the trilobite genus Harpes. From the Black 

 river region has been obtained a large series of the cephalopods 

 of the Black River and Lowville limestones together with a gen- 

 eral representation of the faunas of these formations.
