THE NAUTILUS. 23 



A hermit crab fragment retaining its coloration, sent by Father 

 Stanton, was long believed to be due to foreign ballast, as nothing 

 of the sort was known from the West Indies. The recent acquisi- 

 tion of a bleached but entire specimen from the Florida Keys has 

 confirmed its American habitat. 



The species is nearest the C. guiniacurn Philippi (1849) from the 

 Gaboon, West Africa, but is more conical, and wider in the last 

 whorl, and rather larger. The sharp regular striation and few large 

 rounded ribs are its most striking characteristics. 



AMONG THE CEPHALOPODS. 



BY R. E. C. 9TEARNS. 



According to the papers, the big steamship Northwestern that 

 went ashore last March on La Touche Island, southeastern Alaska, 

 has been floated and is now at Valdez. 



Divers making the survey of the bottom of the sea where the 

 steamer rested, were driven away repeatedly by " great cuttlefish, 

 which swarmed in the vicinity of the wreck." It was feared that 

 these " sea monsters " would prevent the saving of the vessel, but 

 the divers proved game, made the necessary survey, drilled the holes 

 for the dynamite, and laid the charge which blew to atoms the rock 

 that had trapped the steamer, without damaging the vessel.

THE MOLLTSCA OF COLORADO (University of Colorado Studies, 

 vol. iv, no. 2, 3, Feb. and Apr., 1907). By Junius Henderson. 

 This useful addition to the series of state hand-books of mollusks 

 gives an epitome of earlier work by Ingersoll, Cockerell and others, 

 with substantial additions to the list of species (some 25 being here 

 first reported from Colorado), and to the locality records. A key to 

 species and a bibliography are given. Most of the species are illus- 

 trated, the Unionidce by excellent original figures, the snails by cuts
