Falcon Island is also of interest. A valuable series of Siphonaria 

 gigas G. B. Sowerby, from Cantadora Island, Perlas Islands, also 

 several Nacella aenea variety magellanica Gould from Chiloe 

 Archipelago, Chile, were obtained by the "Alva" South American 

 Cruise of 1935. Two exceptionally fine specimens of the rare 

 Helcioniscus argentatu^ Sowerby were collected by the "Ara" 

 World Cruise of 1928-1929, in Hilo, Hawaii. A single specimen 

 of Cymatium nodiferum (Lamarck) was taken at Casa Blanca, 

 Morocco, by the "Alva" Mediterranean Cruise of 1933. 



The Pelecypoda include these species : Area (Navicula) aveU 

 lana (Lamarck) from the Society Islands; a single specimen of 

 the pearly Isognomon perna (Linne) from Falcon Island; a mag- 

 nificent specimen of Reeve's Pteria (Electroma) electrina from 

 Samoa ; young specimens of Pinctada margaritifera (Linne) from 

 the Society Islands and Palm Islands ; a specimen of Pecten zeal- 

 andiae Gray from Samoa, establishing a new locality for this ap- 

 parently rare Pecten; a specimen of Pecten jacoheus Linne from 

 Venice ; specimens of the widely distributed Spondylus nicoharicus 

 Chemnitz from Palm Islands ; also several specimens of the deli- 

 cately beautiful Lima (Limaria) fragilis (Gmelin) from this local- 

 ity, a species which is but sparsely represented in American col- 

 lections; a young Ostrea cucullata Bom, likewise from Falcon 

 Island. An excellent series of the rare Cvltellus scalprum (Gould) 

 was secured in Sourabaya, Java ; this species was hitherto repre- 

 sented in American museums by the type only. 



The Cephalopod collection, though small, contains some un- 

 usually interesting specimens. The rediscovery of the "Chal- 

 lenger" species, Loligo kobiensis Hoyle, hitherto published only 

 from the type material, one adult and four immature specimens, 

 taken in Japan and deposited in the British Museum of Natural 

 History, but now represented in the Vanderbilt collection by three 

 adults from Georgetown, Penang, Malay Straits, greatly extends 

 the southeastern Asiatic distribution of this species. The collec- 

 tion was also augmented by additional material of Loligo dio- 

 medeae Hoyle from the Pacific Coast of Panama, also from Val- 

 paraiso, Chile. The rather rare Loligo indica Pfeffer, collected in 

 series, by the "Ara" World Cruise at Cebu, Cebu Island, Philippine 

 Islands, establishes the first record of it in this archipelago as 

 well as extends the northern distribution of the species. These are 

 the only specimens of L. indica deposited in an American museum.
