XXXIII. — Report upon the Scorpiones and Pedipalpi obtained 

 on the Loxoer Amazons l>y Messrs. E. E. A usten and E. PicJcard 

 Cambridge during the trip of Mr. Siemens^s Steamship 

 ''Faraday.^ By E,. I. POCOCK. 



Though all the species of Pedipalpi broug'lit back by- 

 Messrs. Austen and Cambridge prove referable to previously 

 known species, they are nevertheless of considerable interest 

 as desiderata to the collection of the British Museum and as 

 serving to fill important gaps in our knowledge on points of 

 geographical distribution, constancy of structural features, &c. 

 Of the species of Scorpions, all but one — namely, Brotheas 

 Gervaisii — appear to be nndescribed. The discovery, how- 

 ever, even of this form is of value, since the species was 

 established upon two specimens of which the locality was 

 unknown. The other species are nearly allied to forms that 

 occur in tlie north and north-western countries of South 

 America (Guiana, Colombia, &c.) ; but it is interesting to 

 note that no member of tlie family Bothriuridfe nor of the 

 genera Centrurus, Hadruroides, Garaboctonus, Chactas, Opis- 

 tliacanthus, Diplocentrus, &c., which occur in other parts of 

 the continent, seem to be represented on the Lower Auuizons.
