120 THE NAUTILUS. 



barrel-shaped ; small, about 1.5 mm. in length ; head when expanded 

 elliptical in outline ; anterior ciliated band broken up into segments ; 

 expanded parapodia (wings) flat, long-ovate ; middle lobe of foot 

 rather large." The author gives a very exhaustive account of its 

 general features, musculature, digestive and nervous systems, heart 

 and nephridium, and the reproductive system. The paper is illus- 

 trated by four plates and two figures in the text. — C. W. J. 



The Haliotis or Abalone Industry op the Caltfornian 

 Coast. — By Mrs. M. Burton Williamson (Am. Hist. Soc. S. Cal., 

 vol. vii, pp. 22-30, 1907). An exceedingly interesting account of 

 this important industry. The law protecting these shells is like the 

 law protecting the lobster on the Atlantic. The young are pro- 

 tected but those which produce young are not. The author asks the 

 pertinent question — " If these mollusks are destroyed as soon as old 

 enough to propagate, of what use to the State is the preservation of 

 the young ? " The present method in time can only lead to their 

 extermination. The shells should be protected at least during their 

 breeding period. — C. W. J. 



The Mollusca of Mast Head Reef, Capricorn Group, 

 Queensland, Pt. II. — By C. Hedley (Proc. Linn. Soc. N. S. 

 Wales, vol. 32, pp. 476-513, pis. 16-21, 1907). In this paper 37 

 new species are described and beautifully figured. A list containing 

 some 447 species from this reef, procured within a week, in a six- 

 mile radius from one spot, shows the richness of the fauna. 



The Pyramidellid Mollusks of the Oregonian Faunal 

 Area — By William H. Dall and Paul Bartsch (Proc. U. S. 

 Nat. Mus., XXXIII, pp. 491-534, pis. 44-48, 1907). The species 

 described in this paper have been selected from a monograph of West 

 American Pyramidellidce upon which the authors have been at work 

 for some time, but which has been unavoidably delayed. The 

 Oregonian Faunal Area includes the region extending from the 

 northern limit of the Alexander Archipelago southward along the 

 coast to Pt. Conception, Cal. Thirty-eight new forms are described 

 and beautifully figured together with many others already known 

 imperfectly from this region — C. W. J.
