EXPLORATIONS IN CAPE REGION. 767 



Marine Mollusca. — Described by Dr. J. G. Cooper. 

 The collection was principally made by Mr. W. E. Bryant, 

 during the expedition of 1892. 



Cooper, J. G. Catalogue of Marine Shells, collected chiefly on the Eastern 

 Shore of Lower California, for the California Academy of Sciences, 

 during 1891-2. Vol. v, May 21, 1895. 



Spiders. — During the last two expeditions a specialty 

 was made of spiders. These were turned over to that 

 most prominent arachnologist, Prof. George Marx," of 

 Washington, D. C, but who, through his untimely death, 

 was prevented from finishing the work. In private letters 

 to the writer he stated that there were about three hundred 

 species, mostly new, from the Cape Region alone. 

 These collections, together with those collected during 

 the expedition of 1894, ^^ ^^^ Cape Region and at Tepic, 

 were, after the death of Prof. Marx, forwarded to Prof. 

 Nathan Banks, whose eminent services have been secured 

 in working up the collections. His manuscript is not yet 

 ready. 



Phalangidea or Harvestmen. — All collections made 

 have been sent to Prof. Clarence M. Weed, who has 

 undertaken their description.

 fornia, Cape Region and Tepic, preserved in alcohol, has

Myriapoda or Centipedes. — A very full collection 

 from the Cape Region. The working up of this collec- 

 tion has been undertaken by Prof. R. I. Pocock. The

 and land living species have been sent to Prof. Walter
