Doubtless a host of similar examples can be found within arid! 

 regions. We hope before long to communicate additional results. 



4. Arthrolycosa antiqua of Harger, volume vii, 219, 1874, and 

 xxxviii, 219, 1889. — Justice to Mr. Harger requires it to be stated 

 — what he did not state in his paper — that he was not at liberty 

 to develop any covered parts of the spider on the specimen put 

 in his hands for description. The specimen was regarded as a 

 very valuable one, and the parts of the animal were supposed to- 

 be fully exposed. j. d. dana.

OBITUARY. 



Charles Albert Ashburner. — The able geologist, of Penn- 

 sylvania, Mr. Charles A. Ashburner, died at Pittsburg, on the 24th 

 of December in his 36th year, having been born in Philadelphia 

 in February, 1854. He left the University of Pennsylvania with 

 high honors in 1874, and during the past year received from the 

 University the honorary degree of Doctor of Philosophy. Soon 

 after graduation, on the organization of the Second Geological 

 Survey of the State, he became an assistant in the survey, and in 

 this position the larger part of his geological investigations were 

 carried on. Mifflin, Juniata, McKean, Elk, Forest and Cameron 

 counties were surveyed and reported on by him, and also with 

 great completeness and excellence of maps and sections, the 

 anthracite coal fields which were made his special work in 1880. 

 In 1885, when the director of the survey, Prof. Lesley, com- 

 menced the preparation of his final report on the survey, Mr. 

 Ashburner was put in charge of the executive business of the 

 whole State Survey. In 1887 Mr. Ashburner was given the 

 Bituminous Coal-Region for investigation and report. Subse- 

 quently he became connected with the Philadelphia Natural Gas 

 Company, as an expert, and made Pittsburg his place of resi- 

 dence. Mr. Ashburner was a man of great energy and executive 

 ability, and of thoroughness in all his work, as his various reports 

 show. The Pennsylvania Survey owes much of the value of its- 

 results to his labors.
