Report of the State Geologist. 447 



tainly such a paper would have been more appropriately pub- 

 lished as a bulletin of the State Museum of Natural History, but 

 in this direction publication has been persistently refused. 

 The preliminary work upon the Genera of Lamellibranchiata 



has not been continued, and the bulletin in preparation ten years 

 ago remains without material progress. The bulletin on the 

 Bryozoa proposed, and prepared for publication in 1888 and 1S89 

 yet remains unpublished. The work upon the Dictyospongida*, 

 which was originally recommended to constitute bulletin No. 1 

 of the museum series, has progressed mainly in the direction of 

 the accumulation of material, and the publication of new species 

 in the report for 1889, until the present year. The continuation 

 of the present paper upon the Brachiopoda is already far advanced 

 and it is expected that it will be published in the annual report 

 of the State Geologist for 1893. The second part will include 

 the spire-bearing genera, the Rhynchonellidae, Pentameridae and 

 the Terebratuloids. 



With a continuation of the present provisions for illustrating 

 the report of the State Geologist, we may hope within a few 

 years, to retrieve in some measure, the loss of time and publica- 

 tion, suffered during the past ten years.
