678 Zoology. 



Spiders of the families Cluhionidx, Thomisidx, Lycosidse, Argiopidx, 

 etc., completing the series, were received from M. Simon in 1897. 



Whitehead (John). 



From 1894-1896, series of Arachnida collected by Mr. J. Whitehead 

 in the Philippines were presented by the subscribers to the "Whitehead 

 Expedition. These collections were almost the first properly preserved 

 material received by the Museum from the Philippines. 



Yerbury (Col. J. W.). 



From time to time since 1892, Colonel Yerbury has collected and 

 presented to the Museum a large number of Arachnida from Ceylon 

 and a valuable collection of Scorpions from Aden and the neighbourhood. 

 He has also added to the collection of European Arachnida by donations 

 of specimens from Corsica, Portugal, and different parts of the British 

 Islands. 



II. Order XIPHOSURA. 



The curatorial history of the King-Crabs is the same as that 

 of the Crustacea down to 1893, when the care of them was 

 transferred to the assistant in charge of the Arachnida. 



The earliest specimens received by the Museum belonged to 

 Dr. Leach's collection, which was acquired by the Trustees in 

 1826. These were entered in the first volume of the MS. 

 catalogue of Crustacea (pp. 1-3). The date of this catalogue is 

 unknown ; but since the specimens of Limulus belonging to the 

 Hardwicke Bequest, which was received in 1835, were entered on 

 p. 3 in the same handwriting as that in which Leach's specimens 

 were entered, it is evident that the date of the commencement of 

 this catalogue cannot be earlier than 1835. This handwriting- 

 appears to be that of J. E. Gray, or of an attendant, S. Parr ell. 

 Subsequent accessions were entered by the same hand, with 

 additions by Adam White, on pp. 535-536, in the second 

 volume, and on pp. 1031-1033 in the third volume. A MS. 

 hand-list of the specimens contained in the collection was com- 

 piled by the last-named author. The date of this is uncertain, 

 but since it contains an entry of specimens received from Edw T ard 

 Blyth in 1846, it cannot be earlier than that year. 



From 1838 to 1876 accessions were recorded in the " Insect " 

 Register, together with the rest of the Arthropoda ; from 1876 

 to 1893 in the Register set apart for Crustacea, and from 1893 to 

 1900 in the Register of Arachnida and Myriopoda.
