 vicinity of Valles. 



Bulimulus schiedeanus Pfr. One dead specimen, Tampico. 



Drymseus multilineatus Say. Valles. A few dead ones with 

 colors nearly as bright as in life. Pilsbry says " The specimens are 

 almost exactly intermediate between D. multilineatus and D. dis- 

 crepans Sowb., having the coloration of the latter except that the 

 apex is dark bluish, as in multilineatus. There is no dark subsutural

THE MOLLUSCA OF THE PERSIAN GULF, GULF OF OMAN AND 

 ARABIAN SEA, ETC.* Pt. II, Pelecypoda, by James Cosmo Melvill 

 and Robert Standen. (Proc. Zool. Soc., London, 1906, pp. 783- 

 848, pis. 53-56.) 



In this part some 426 species are enumerated, of which 35 species 

 are new. The richness of the fauna is dwelt upon, the total number 

 of mollusca recorded from this area being 1618. The two parts 

 constitute a valuable addition to our knowledge of mollusks of this 

 region.
