contrary, the intestinal nerve follows tlie course of the intes- 

 tine ; it is frequently furnislied with ganglia along its course, 

 from which arise branches supplying the intestine, and there 

 is but a slight formation of plexuses round some of the intes- 

 tinal blood-vessels. This intestinal nerve is one of three 

 principal nerves arising from the sympathetic chain and sup- 

 plying the alimentary tract, the others being the great and 

 little splanchnic nerves ; it is compared to the inferior me- 

 senteric nerve of Monitor niloticus. 



78. Menzbier and Sewertzow on the Ornithology of Turkestan. 



[Dr. N. A. Sewertzow, Ornithologie du Turkestan et des Pays ad- 

 jaceuts. (Partie N.O. de la Moiigolie, steppes Kirghiz, contree Aralo- 

 Caspienne, Partie sup^rieure du Bassin d'Oxus, Pamir.) Par M. le 

 DocteurM. A. Menzbier. Livr. 1. Text and Atlas folio. Moscou: 1888.] 



Severtzow had long planned a great work on the birds of 

 Turkestan, and at the time of his premature death in 1884 

 was on the point of putting his plans into execution. It has 

 now fallen to M. Menzbier, whom Severtzow had proposed 

 to associate with himself in the undertaking, to take sole 

 charge of this important work, and we have here the first 

 installation of it. 



The first livraison contains the commencement of the 

 account of the Diurnal Accipitres. Amongst them are in- 

 cluded several forms [Aquila nobilis, A. daphanea, A. amu- 

 rensis, and A. glitchii) which are not generally recognized in 

 Western Europe, and of which we are glad to have full 

 particulars, whatever may be our opinion on their specific 

 validity. 



The atlas contains good coloured lithographs of Astur cen- 

 chroides, Hierqfalco hendersoni, Falco babylonicus, and Cyan- 

 istes flavipectus.
