PUTNAM ON GALEODES PALLIPES. 35 



the Iowa shore of tlie river, somewhere l>etween Dubuque aiul 

 Davenport, while on his way down tlie river in 1871. He 

 thought it was in Scott county, but couhl not l)e positive. It 

 was decided that this species shouhl be dropped from tlie list 

 until better evidence is secured. A variety of other phmts were 

 discussed. 



Mr. W. H. Pratt exhibited a glass of cistern water contain- 

 ing a number of very small and active crustaceans, a species of 

 Cyclops. Several of these were placed under a microscope and 

 examined with interest l)y the members present. Mr. Putnam 

 stated that he had frequently noticed these crustaceans in the 

 well water at his residence in the west part of town. Their 

 presence in the water should be regarded as rather a tavorable 

 sign. They probably act as scavengers in destroying organic 

 matter that might otherwise be injurious. 



Mr. J. D. Putnam exhibited several specimens of a curious 

 spider-like animal, belonging to the Soljyugidie^ a family of 

 Arachnids allied to the scorpions, and made the following re- 



mai'ks on 



Galeodes pallipes. Say. 



The specimens here exhibited, five in mnnber, were collected at differ- 

 ent times in 1872 and 1874, under stones and dried dung in dr.y places, 

 near Denver, Valmont or Canon City. Colorado. They were always, 

 found single and alone. As near as I can recollect I have never noticed 

 any other living thing under the same stone with them. They appear to 

 be quite pugnacious, but their habits were not as carefully observed as 

 they should have been. 



This species was first collected over fifty years ago by the celebrated 

 naturalist of Philadelphia, Thomas Say. at the base of the Rocky Moun- 

 tains, not far from the site of the present city of Denver, and was des- 

 cribed by him in a foot-note in the Report of Long's Expedition to the 

 Rocky Mountains in 1819-20, under the name of Galeodes pallipes. In 

 the same place Mr. Say describes another species — G. siibuhtta. Of this 

 latter species but one specimen is known to have been since collected — 

 by Capt. Marcy on his expedition to Red River in 1852, and is redescribed 

 by Girard in the report of that expedition. This specimen is still pre- 

 served in the museum of the Academy of Natural Sciences in Philadel- 

 phia, and although only hastily examined I am satisfied it is quite dis- 

 tinct from my Colorado specimens. Dr. Packard in his Guide to the 

 Study of Insects mentions that Solpnga {Galeodes) Americamis Say, oc- 

 curs in the Southern States, but no authority is giveu, nor can I find 

 any other reference to such a species. At the meeting of the Philadel- 

 phia Academy of Natural Sciences Nov. Tth, 1870, Prof. Cope exhiljited
