4 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 124 



fied set of specimens also has been deposited in the Museum National 

 d'Histoire Naturelle, Paris (MNHNP). The abbreviation IIOE 

 identifies material obtained through the International Indian Ocean 

 Expedition. 



I thank Michel Pichon, Arthur G. Humes, and Alain Crosnier for 

 making collections available for study; this report would not have 

 been so complete without the large collection received from Crosnier. 

 L. B. Holthuis, Kijksmuseum van Natuurlijke Historie, Leiden, 

 loaned a syntype of Sqvilla harpax de Haan, and Claude Michel, 

 Mauritius Institute, allowed me to borrow the type of Squilla juxtaora- 

 toria Ward. 



The illustrations were made by my wife Lilly with the support of 

 the Smithsonian Institution through its Research Awards program. 



Clorida Eydoux and Souleyet, 1842 



With the recent description of two species from India (Chhapgar 

 and Sane, 1967) and a new species from Madagascar described herein, 

 the genus Clorida now comprises 16 species, all of which occur in the 

 Indo-West Pacific region. In view of the large number of species now 

 placed in the genus, it is felt that the key to species presented below 

 will be of some aid to other students of the group. 



The key does not include Sqvilla gibba Nobili, 1903, a species aligned 

 with Clorida latreillei Eydoux and Souleyet and its allies by previous 

 workers. I have transferred Nobili's species to another genus in a 

 paper now in press (Manning, 1967c). 



Five species have been recorded from the Western Indian Ocean, 

 including records given herein. Clorida latreillei has been recorded 

 from southern Mozambique by Barnard (1926, 1950), and C. micro- 

 phthalma (H. Milne-Edwards) has been recorded from Zanzibar by 

 Jurich (1904) and Stephenson (1962). Either of these two species 

 could occur off Madagascar.
