OCCURRENCE OF GADINIA RETICULATA, Sow, IN 

 SOUTH-EASTERN POLYNESIA. 



By Andrew Garrett. 

 Having collected a number of examples of a species of 

 Gaaittia, in the Society and Paumotu Islands, the first indication 

 of the genus in Polynesia, I distributed them among my corres- 

 pondents, labelled G. varia, Nobis, MS. Having received a fine 

 series of So.verby's reticulata, collected in California, I cannot 

 detect after a critical comparison the slightest difference in the 

 specimens from the two localities, they agreeing precisely in form, 

 texture, color and sculpture. Our shells were found adhering to 

 the under side of huge blocks o' dead coral on the outer reefs, 

 where they were continually submerged except at extreme low 

 water at the new and full moon. 



OCCURRENCE OF CREPIDULA ACULEATA, Gmel., 

 IN THE MARQUESAS ISLANDS. 



By Andrew Garrett. 



About a year ago, while exploring the Marquesas, I remarked this 

 cosmopolitan species cast up on the beaches in great numbers, 

 though seldom in good condition. It is probably a denizen of 

 deep water, as I searched in vain for living examples. 



It also occurs at the Sandwich Islands, where I found a few 

 beach-worn specimens. It is recorded from New Zealand, Aus- 

 tralia, India, Mau.itius, W. Indies, Japan, Panama and California. 

 I have had no opportunity of comparing our shells with West 

 Coast examples. 



Having lately received perfect specimens of Hippoiiyx bar- 

 batus, L., and H. antlquatus, L., from the coast of California, 

 I failed to discover even a single varietal character to separate 

 them from Polynesian examples. The former species is not un- 

 common in all the Eastern Polynesian I,->lands, and antiquatus
