PART V 



SYSTEMATIC DISCUSSION 

 CRUSTACEA 



The Crustacea presented in this Bulletin of the Vanderbilt Ma- 

 rine Museum, are a part of the collections obtained by Mr. William 

 K. Vanderbilt during a series of cruises on his yachts "Ara" and 

 "Alva" during the years 1928 to 1935. These expeditions included 

 the World Cruise of the yacht "Ara," 1928-1929, the World Cruise 

 of the yacht "Alva," 1931-1932, which has contributed also the 

 Crustaceans collections reported in the Bulletin of the Vanderbilt 

 Marine Museum, Volumes V and VI, the "Alva" Mediterranean 

 Cruise of 1933, and the "Alva" South American Cruise of 1935. 

 The thirty-five species herein discussed include Stomatopoda, 

 Brachyura, Macrura, Anomura and Cirripedia. 



Only two species of Stomatopoda are present, Lysiosquilla 

 maculata (Fabricius) from Hawaiian waters and the very rare 

 Squilla gilesi Kemp, represented by two very fine specimens from 

 Singapore, a record which very definitely extends the southern 

 range of this species. 



The Brachyura are represented by nineteen species, ten of 

 which are quite rare. Raninoides loevis Latreille from the Pearl 

 Islands (Boone, 1930) discussed in the present volume, is of 

 exceptional interest, since the specimens in the Vanderbilt col- 

 lections definitely establish the presence in the American tropical 

 Pacific of this rare frog-crab, hitherto known only from the 

 tropical and subtropical east coasts of the Americas. 



Calappa philargius (Linne), one of the rarest species of this 

 interesting genus of box-crabs was taken in Singapore by the 

 "Ara," adding a new locality for it, to the less than twenty reliable 

 records for this exquisitely sculptured crab which has been knowTi 

 since 1758. The better known Calappa hepatica (Linne), previ- 

 ously described in these bulletins from material obtained by the 

 "Alva" World Cruise in the Society Islands, was also taken by 

 the "Ara" in Hawaii. 



The spider crabs are represented by three rare, deep-water 

 species. An exceptionally fine series of Anasimus fugax A. Milne 

 Edwards dredged by the "Alva" off Sombrero Light, Florida, in
