Riippell's Travels in North Africa. 393 



figured by M. Temminck in the Planches Coloriees, and perhaps synony- 

 mous with the Mycteria Senegalensis, Vieill.: and the Ciconia Abdimii, 

 Licht., " Cic. viridi-purpurea; ventre et uropygio albis; facie gulaque 

 " nudis ; clypeo frontaU depresso ; rostro pedibusque virescentibus; pedum 

 " articuUs rubris." In the name of this species the Prussian travellers 

 Ehrenberg and Hemprich, have commemorated their gratitude for the 

 hospitality of the Nubian chief Abdim-Bey, to whose kindness was 

 owing much also of Riippell's success. 



The jYatatores comprise the Pclecanus rufescens, Lath. : the Sterna 

 velox, " Sterna rostro flavo ad basin virescente; capite supra nigro; 

 *' regione frontali, malari, temporali, collo, et toto corpore inferiore 

 " candidissime albis; dorso, uropygio, cauda, et alis, obscur^ cinereis; 

 " pedibus nigris:" the Sterna affiuis, " Sterna rostro flavo; fronte 

 " capiteque nigris; regione malari, toto collo, et corpore inferiore, 

 " candidissime albis; dorso, remigibus, et rectricibus, argenteo-cinereis; 

 " pedibus nigris:" both the latter being from the Red Sea : the Rhijn- 

 diops orientalis, " Rhynch. fronte, parauchenio, totoque corpore inferiore 

 " albis; superiore fusco-atro; rectricibus fuscescentibus, albo margina- 

 " tis; rostro sanguineo, apice flavescente," synonymous with the Rhynch. 

 albirostris, Licht., the description and name of which must have been 

 taken from a bad specimen with the bill bleached : and the Lams 

 ichthyatus, Pall., the range of which appears to be extremely wade, it 

 being found not only on the Red Sea, but also on the Caspian, and on 

 the Ganges aud other large rivers of Hindoostan. 



Only three Reptilia have yet been figured: the Stellio vulgaris, 

 Daud. : the Agama Sinaita, " Ag. corpore ex fuscescente griseo, maculis 

 " dilutioribus ; squamae dorsales sequales, subcarinatae, marginatae; 

 " limbus auriculse unispinosus; scutella analiasex:" and the Uromastyx 

 ornatus, " Urom, obscure viridis ; corpore fasciis citrinis irregularibus ; 

 " segmenta subcaudalia squamis inermibus, serie simplici dispositis." 

 The latter differs by its larger, fewer, and flatter scales, which are not 

 spined round the ears, on the sides of the neck and back, and on the 

 anterior leg's, from the two other species found by M. Riippell, the Urom. 

 spinipes, Merr., (of which the follovnng character is given in a note, 

 " Urom. supra obscure viridi-fuscus (mas et faem,) ; segmenta subcau- 

 " dalia squamis dentatis, in series plures dispositis:") and the Urom.
