The feature of this work is the excellent series of coloured 

 maps, in which the distribution of nearly all the diurnal 

 Raptores known in Switzerland is clearly indicated, the ex- 

 ceptions being those species which are widely diffused, and a 

 few of rare occurrence, such as Falco gyrfalco and F. lanarius 

 [? F./eldeggi]. We are sorry to reroark the gradual dimi- 

 nution in the number of the haunts of the Bearded Vulture 

 from 1860 to 1888 as compared with those occupied from 

 1801 to 1859, and the same may be said of the Golden 

 Eagle ; but unfortunately there is the same greed in Switzer- 

 land for home-killed specimens of such birds as there is in 

 Great Britain. 



91. " Timehri/ Vol. II. (new series) Pt. 2. 



['Timebri,' being tbe .Tournal of the Royal Agricultural and Com- 

 mercial Society of British Guiana. New Series. Vol. II. Part 2. 1888.] 



Amongst the contributions to the number of ^ Timehri ' 

 lately issued is an account by Mr. Quelch of a fortnight^s 

 collecting-trip up the Abary Creek, in British Guiana, which 

 contains many notices of birds. Mv. Quelch was somewhat 

 surprised to find the Hoatzin {Opisthoconms cristatus), locally 

 called " Hanna " along the creek, as plentiful as this strange 

 bird is known to be in the Berbice Biver and Canje Creek. 

 On the Abary Creek these birds were all moulting in Oc- 

 tober and in poor condition. Their crops contained only 

 leaves of the "Mucco-mucco^^ {Montichardia arborescens), 

 whereas on the Canje they were found to feed only on the 

 leaves of the Pimpler {Drepanocarpus lunatus).
