Monbuttu, but ratlier browner, and tlie large wliite blaz6 

 disting-uislies tliat larger species. The skull most nearly 

 resembles G. Bocagei from Angola in having a very broad 

 facial portion and in the nasals ending in a point level with 

 the back of the intermaxillary processes ; the zygomata are, 

 however, much lighter, the inner surface is perpendicular and 

 not turned upwards, and the maxillary processes do not spring 

 out so abruptly ; the infraorbital foramina are very small, not 

 more than 1 millim. high and ^ millim. broad ; the teeth are 

 large in proportion ; the auditory bullae rather fuller than in 

 most of its allies. In the mandible the coronoid processes 

 are very much shorter and further from the condyle; the 

 intermediate space is level, being in this respect more like 

 G. Darlingi from the Salisbury Plateau of Mashunaland. 



The type (no. 97. 12. 5. 2 in the British Museum) was 

 collected and presented by Major F. D. Lugard, D.S.O., G.B., 

 who obtained it in the Kalahari Desert between Palapye and 

 Ngami. 



Measurements (taken from the dried skin) : — 



Head and body (c.) I;i0 millim.; tail 13 ; hind foot 25. 



Skull : greatest length 34 ; breadth of brain-case 14'6 ; 

 nasals I2x3"2; breadth of facial portion 8"3 ; intertemporal 

 constriction 8 ; basal length 30 ; molar series I'D ; mandible, 

 back of incisors to back of condyle 22*5, to coronoid 14*5. 



Major Lugard also brought liomeaGalago [Galacjo maholi) 

 taken at Palla, Bechuanaland Protectorate, which adds to our 

 knowledge of the range of this species. 



XLI. — On the Habitat of the Sihiroid Fish Anoplopterus 

 platychir, Gthr. By G. A. Boulexger, F.R.S. 



Among some fishes collected in Northern Nyassalaad, biitween 

 Kondowe and Karonga, by Mr. A. Whyte, and presented to 

 the British Museum by Sir H. H. Johnston, I was rather 

 surprised to find two specimens of a catfish of the genus 

 Anoplopterus^ PfefFer, which, instead of being referable to the 

 recently described East- African A. uranoscopus, PlefFer, 

 agreed in all respects, except their larger size (75-80 millim.), 

 with Giinther's A. plafi/chir. The fish was originally 

 described, from Sierra Leone specimens, as a Pi/nelodus, 

 from which genus Anoplopterus differs in the absence of an 

 ocular rim and of any trace of ossification in the first dorsal 

 ray. Almost at the same time the fish reached me a paper
