The Opisthobranchiate Mollusca of the Branner-Agas- 

 siz Expedition to Brazil, by Frank Mace MacFarland (Leland 

 Stanford Junior University Publications No. 2, 1999). — The follow- 

 ing species are described : Tethys dactylomelu (Kang), T. cervina Dall 

 and Simpson, Pleurobranchus ayassizi, Discodoris brayineri, D. voni- 

 heringi, Peltodoris greeleyi and Spurilla braziliana nov. spp. The 

 internal anatomy of all the species is fully described and illustrated 

 with excellent figures. Professor MacFarland's excellent work on 

 Opisthobranchs is making amends lor the neglect of the group by 

 American zoologists H. A. P. 



NOTES. 



Albino Oliva angulata We have recently received for 



examination a large and perfect specimen of Oliva angulata which 

 is snow-white except for a small fleshy-brown stain on the callus at 

 the posterior angle of the aperture and a rusty yellow stain in front 

 of the callus. This albino, which may be called form nivea, is the 

 first to be reported of this species, so far as we know. It seems to 

 be an extremely infrequent variation. The specimen measures 83 

 mm. long, 42.5 wide. It is the property of the A. L. Hettrich Com- 

 pany, of San Francisco. — H. A. Pilsbry.
