I. 



Stalked Barnacles from Western Malaysia. 



Of Stalked Barnacles already known from the western section of the Malay Archipe- 

 lago, the Indian Museum possesses examples of the following, none of which have hitherto 

 been included in the Indian l Marine Fauna : — 



1. Pcecilasma amygdalum, C. W. Aurivillius, 1894. 



One specimen from the Andamans. Previously known from Java. 



2. Dichelaspis equina, Lanchester, 1902. 



Numerous specimens on the limbs and carapace of Doclea ovis and other crabs 

 from shallow water off the Ganjam Coast. They exhibit the same variety as regards the 

 terga as that noted by the author of the species (P.Z.S. 1902 (2), p. 376), but the 

 membrane is uniformly opaque.- Previously known from Trengganu, Malay Peninsula. 



3 . A lepas indica , Gru vel ,1901. 



Several specimens on floating wood from the Nicobars. The only locality hitherto 

 recorded is Singapore. 



The specimens on which the new species described below are based were presented to 

 the Indian Museum by Capt. F. Worsley and the Eastern Telegraph Company. As very 

 few Barnacles have been reported from the same part of Malaysia, it is not surprising 

 that they should be new. They are distinct from any dredged by the R.I. M.S. Ship 



l It should be noted that Continental writers on Marine Zoology, use the term " Indian," or its equivalent in their own lan- 

 guages, with a wider significance than British and Indian naturalists usually adopt. Hcek's Scalpellum indicum comes from the 

 Banda Sea, while Gruvel includes Singapore in Vlnde Anglaise. 



* This is not the case with some specimens which I have lately examined in Ceylon. All our specimens in the Indian 

 Museum are very small. Oct. 4th, 1905.
