680 Zoology. 



1879-1884. 



A specimen of L. rotundicauda, collected by Dr. Cantor in 

 Penang, was transferred from the Indian Museum in 1879 ; in 

 1880, a specimen of the same species and one of L. moluccanus, 

 collected by Dr. P. Bleeker, were purchased, and in 1884 two 

 examples of L. tridentatus from Swatow in China were received 

 from the Commissioner of the Chinese Court of the Fisheries 

 Exhibition of 1883. 



1897. 



Three examples of L. tridentatus from Kudat in British 

 North Borneo were presented by G. W. Johnstone, Esq. Also 

 two examples of L. tridentatus from Kudat, three of L. moluccanus 

 from Brunei and the Gulf of Siam, and two of L. rotundicauda 

 from the Gulf of Siam, collected by Capt. S. S. Flower, were 

 received in exchange from the Royal Museum, Bankok. 



III. Order PYCNOGONIDA. 



The Marine Arachnida of this order were formerly attached 

 to the collection of Crustacea, and until 1893 were in the 

 charge of the same curators and entered in the same registers 

 as the Crustacea. In 1893 they were transferred, with the 

 Xiphosura, to the care of the assistant responsible for the 

 Arachnida. Scarcely any special attention in the way of 

 systematic descriptive work has ever been paid to this group. 

 Beyond the registration and provisional determination of acces- 

 sions it has been impossible to give time to working it up. 

 Consequently at the present time the collection is hardly up to 

 the standard of excellence attained by that of some continental 

 museums, although the material obtained on the " Challenger :; 

 expedition is of exceptional value. Previous to the arrival of 

 this collection, the Museum material had been determined by 

 Mr. Adam White and Mr. E. J. Miers, both of whom established 

 a few new species. Since that date all the identified material 

 has been received from external sources, principally from the 

 Museums of Christiania and Copenhagen and from the Norman 

 collection.
