Dr. Gould exhibited what appeared as a brilliant carmine 

 p^der, obtained from a carpet. It proved to be a group 

 of minute arachnids, allied probably to the genus Coptus 

 (Latr.) ; most of them were living. 



Dr. C. T. Jackson announced the decease of Dr. John 

 Evans, a corresponding member of the Society, who died at 

 Washington, on April 13, of pneumonia. 



He spoke of the valuable services of Dr. Evans as a geolo- 

 gist, and proposed the following resolution, which was 

 seconded by Mr. Marcou, and unanimously adopted : — 



Resolved, That the Boston Society of Natural History have learned 

 with deep regret the decease of their corresponding member, Dr. 

 John Evans, United States Geologist of Oregon and Washington 

 Territories and of the Chiriqui Expedition, and deplore the loss 

 which the country has sustained in the death of this active and enter- 

 prising geologist. 



It was voted that a copy of this resolution be sent to his 

 widow, Mrs. Sarah Z. Evans, at Washington, D. C. 



Mr. Marcou exhibited Boue's geological map of the world, 

 and portions of a map in course of preparation by himselt*

 Boue's. The portions exhibited were N'orth and South 

 America ; these were printed in colors, and were difficult to 

 execute as well as very expensive. Among the recent dis- 

 coveries that he was able to indicate, is the occurrence of 

 Jurassic strata on the coast of Greenland and Arctic 

 Ameiica. 



Dr. Jackson observed that these tentative maps, on which 

 what is actually known is put in distinctive colors, and the 

 unknown and unexplored left blank, are of great value to
