Barnacles from deep-sea Telegraph Cables 

 in the Malay Archipelago.

Man}* years ago Capt. F. Worsley of the S. S. ' Sherard 

 Osborne ? obtained a number of deep-sea barnacles from cables that 

 his ship was engaged in repairing. Some of these he presented to 

 the Indian Museum in Calcutta, the others (the major part) to 

 the Baffles Museum in Singapore. Those in the Indian Museum 

 were described by me in 1905 in the Memoirs of the Asiatic Society 

 of Bengal; I have now to thank Dr. Hanitsch for the opportunity 

 of examining those in Singapore and of comparing selected speci- 

 mens with the collection in Calcutta. 



There is one slight uncertainty as to the provenance of the 

 Singapore specimens. A large portion of them are stated to have 

 been found in lat. 10° 22' 30", but it is not stated whether North 

 or South. There can, however, be little real doubt that South is 

 meant, for the corresponding specimens in Calcutta are labelled 

 " Bali Straits." 



The majority of the specimens are from Bali and Gasper 

 Straits and the Java Sea. There is also one species from off 

 Timor. Probably all were brought up from depths of between 60 

 and 200 fathoms, except Heteralepcts malaysiana, the type-specimen 

 of which came from 30 fathoms. 



A remarkable feature of the collection is the very large pro- 

 portion of otherwise unknown forms represented in it. In the 

 following list those species that are recorded also from other sources 

 are distinguished by a star at the end of their names.
