THIRD NOTICE OF NEW SPECIES OE EISIIES FROM 



MOROCCO. 



By dr. a. gunthei;, f.r.s. 



(Plates XXII, XXIII) 



THE small collection of fishes obtained by Mr. Hartert in the Oiiiu Erbiah,* 

 aud described by me in this Journal, Vol. VIII, p. 367, was sufficiently 

 encouraging to induce a correspondent of Mr. Hartert, Hrn. F. W. Riggenbach, 

 who resides at present at Mazagan, to pay some attention to the subject. He has 

 forwarded to the Tring Museum a small collection from the same river, by which 

 our knowledge of its fishes is further advanced. All the si)ecimens were obtained 

 either in the main river, or in a small trilmtary, the river Talmist, not farther than 

 about twenty-five or thirty miles from Mazagan, or, in other words, (juite within 

 the lowermost reaches of the river. 



Beside the species described in my i)rcvions paper, four others were represented 

 in the present collection, viz., Mugil rapito, Angiiilla vxlffarits, and two undescribed 

 Barbels, Barhus rigqenhachi and I'terocapocta maroccana. The collection offers 

 also supplemental information on the s])ecies previously described. Wc may well 

 assume that the eight species now known from this river are only a fraction of the 

 species inhabiting it. 



Pterocapoeta gen. nov. Cyprin. 

 Scales of moderate size. Dorsal fin without osseous ray, and with more than 

 nine branched rays, commencing in advance of the ventrals. Snout broad, obtusely 

 rounded, projecting beyond the mouth. Mouth inferior, transverse, slightly arched, 

 none of the margins crenulated or fringed ; each mandible angularly bent inwards 

 in front, with a sharp edge covered with a fle-xible horny integument ; no lower 

 labial fold; no symphysial tubercle. Barbels two, rudimentary or absent. Anal 

 scales not enlarged. Pharyngeal teeth, 4, 3, 2, comjiressed, truncated. 



Pterocapoeta maroccana sp. nov. (PL XXII). 



D. 13-14 ; A. S ; V. Ki ; L. lat. 4.5 ; L. traiisv. ,sj-s. 



The height of the body is contained 4^ times in the total length (without 

 caudal), the length of the head 4§ times. Head small and broad ; eye rather small, 

 not quite one-sixth of the length of the head, or two-fifths of the broad aud convex 

 interorbital space. Snout very broad and thick, much projecting beyond the month, 

 jiarticnlarly so in the largest individnal. The barbel is minute, hidden in the 

 grove near the angle of the month, and not always visible. The horny edge of the 

 mandible extends a little way inside the mouth, the mucous membrane behind it 

 being wrinkled, the folds running in the longitudinal axis of the fish. The first 

 dorsal ray is a little nearer to the end of the snout than is the last to the root of 

 the caudal ; dorsal fin a little higher than long. Anal fin narrow, not or scarcely 

 reaching caudal. Caudal fin deeply forked, with pointed lobes. Pectoral fin

 Um-er-Kebia, Rio Morbeja, Waad Moorbey, Moorbey River.
