12 THE NAUTILUS. 



a tawny yellow dorsal stripe, the latter a dark form without any 

 stripe. These molluscs are the first real representatives of their 

 genus found in Australia, the only Vaginula previously known 

 here, V- australis, Heyneman, belonging to that trigonal group 

 which embraces V. prismatiea, Tapparone-Canefri, from Dutch 

 Xew Guinea, V. tourannends, Souleyet, from Cochin-China, 

 and V. trigona, Semper, from the Philippines, constituting a 

 natural but as yet unnamed genus. He also took the opportunity of 

 j)ointing out that he had submitted specimens of Lunax queens- 

 landicus, Hedley (P. R. S. Q., Vol. V, ]). 150, pi. 5), to Dr. Sim- 

 roth, who had determined them to be Agriolimax kevis, Miiller. 

 This species is probably the slug (Journ. des jNIus. GodefF., XII, p. 

 159) mentioned under the name of L. rarotonganiis, Heyn., as occur- 

 ring in Au.stralia. Few if any land molluscs range so widely, since, 

 under different names by various authors, this form has been re- 

 corded from Europe, North and South America, the West Indies, 

 Madagascar, and many islands of the Pacific. — From advance proof

Dr. JosiM'H Lkidv, 



Professor Joseph Leidy, jNI. D., LL. D., the eminent scientist, 

 <lied at his home in Philadel])hia on A])ril 30th, 1891. Dr. Leidy 

 w'as born in Philadelphia, Se])t. 9, 1823. His ancestors on both 

 sides were Germans, from the valley of the Rhine. His taste for 

 natural history was exhibited at a very early age, and when a mere 

 boy he collected and studied minerals and plants. His father pro- 

 posed for him the career of an artist, but so absorbed was the boy 

 in anatomical and natural history studies that, with the encourage- 

 ment of his mother, at the age of seventeen he began the study of 

 medicine, graduating in 1844. In 1845 he was appointed Prosector 

 to the Chair of Anatomy in the University of Pennsylvania. Dr. 

 Leidy's first scientific work was a paper on the anatomy of Litorina, 

 published by the Boston Society of Natural History. In 1844 he 

 began, at the instance of Dr. Amos Binney, to study the anatomy 

 of land snails. The result is seen in his beautiful anatomical draw- 

 ings in the first volume of Binney's "Terrestrial Mollusks," and in 

 the chapter on special anatomy written by him. In 1845 Dr. 

 Leidy was elected a member of the Academy of Natural Sciences of 

 Philadelphia. He has been closely connected with this institution
