L. philippi in the collections of the British Muséum (Nat. Hist.), London, and agrée with 

 CooKE and Smith that they ail represent différent stages in growth of the same species. The 

 small différences in form of the shell, as was pointed out by Smith, are of no importance for 

 the distinction of the species, and the shells of the above noted species do not show any other 

 différences either in the sculpture or the hinge. 



Distribution: — L. imiltistriata is widely distributed in the Red Sea and the Indo-Pacific. 



In the "Siboga" collection it is represented by a half-grown spécimen and a few young 

 shells collected at Anchorage off Ubian (St. 99), Sulu Harbour, Sulu Islands (St. 104), Anchorage 

 off Pulu Tongkil, Sulu Archipelago (St. 109), St. 300 (io°48'.6S., i23°23'.iE.) and St. 321 

 (6° 5^5 S., ii3°3o'E.).

After comparison of the "Siboga" spécimens from the localities enumerated below with 

 the types of L. indica Smith, in the Indian Muséum, Calcutta, I hâve no doubt that they ail 

 are to be referred to this species. Ail the spécimens are greatly weathered and worn and on 

 none of them any trace of the pilose epidermis or of the sculpture is to be distinguished. The 

 largest shell is 11.8 mm. long and 16.7 mm. high. 



Distribution : — L. indica had so far been recorded from off Ceylon and off Maldive 

 Islands in the Arabian Sea. 



In the "Siboga" collection there are spécimens from St. 95 (5°43^5 N, ii9°4o'E.) and 

 St. 208 (5° 39' S., 122° 12' E.). 



3. Lùnopsis lata Smith. (Plate II, figs. 7, 8).

191 5. Limopsis lata Suter, Man. New Zealand MoU., Atlas, pi. LI, figs. 9, ga. 



Smith's description of L. lata is very detailed, and needs no élaboration. His comparison 

 of the species with L. minuta (Philippi) ^) however, in view of the materially différent hinge in 

 the two species, is far from justifiable. 



Both Lamy -) and Suter followed Smith in comparing L. lata with L. minuta, but it is 

 not possible to understand Lamy's remark that the former is distinguished from the latter 

 "surtout par sa largeur". The sculpture and hinge of the two species are very différent and 

 there can be no question about the two species being distinct. 



Distribution: — L. lata was described from spécimens obtained by the "Challenger" off 

 the coast of New Zealand in 700 fathoms.
