Superfamily PANDALOIDA. 



Family Thalassocaridae. 

 Thalassocaris Stimps. 



This genus, the only one of the family, includes at present four species and one variety. 

 Thalass. Danae Bate, which was taken near the Fiji Islands at the surface, should, as was already 

 suggested by Dr. Balss (Ostasiat. Decapoden, II, 1914, p. 27), be regarded as an immature form, 

 probably of Thalass. lucida (Dana), while Thalass. Stimpsoni Bate seems to be a larval form, 

 probably not pertaining to this genus. All the species are indopacific. Thalass. crinita (Dana), fust 

 recorded from the Sulu Sea, was also taken by the "Siboga" at two Stations of the Sulu Islands, 

 furthermore off Biaru-island, near the north point of Celebes and between Nusa-Besi and the 

 N. E. point of Timor; this species occurs in the Western Indian Ocean and has also been 

 observed at Dzushi, Japan, while a variety was captured by the "Siboga" off the island of 

 Saleyer. Thalass. lucida (Dana) has been found off Assumption Island, one of the Ladrones, 

 west of the Bonin-islands, in the Pacific and near Christmas Island : this species will therefore 

 certainly prove to occur also in the Indian Archipelago. The two other species, Thalass. affinis 

 Borr. and Thalass. maldivensis Borr., are known from the Maldives and Saya de Malha. 



The species of Thalassocaris are found in shallow water.
