in width and much more brightly coloured posteriorly. Tail 

 yellow, passing into a redder tint posteriorly ; the lower 

 surface of the first segment is furnished behind with two 

 abbreviated black lines, that of the third has the corresponding 

 lines better developed and a slender median line which takes 

 its origin from a conspicuous black spot on the anterior 

 portion of the segment ; ornamentation of the same kind is 

 noticeable upon the lower surface of the two following seg- 

 ments, but it is less clearly defined on the fourth. 



Legs and paJpi yellow ; digits infuscate. 



Thorell's type from CafFraria was doubtless a male, since 

 no reference is made to the enlargement of the basal pectinal 

 tooth observable in my example, in which there are 18-19 

 teeth, the basal being modified as in U. occidentalis and 

 lineatus, and not elongate as in U. planimanus and lumdifer. 

 This specimen also differs in two other respects from Tliorell's 

 description, since it possesses twelve rows of teeth along the 

 middle line of the digits, instead of eleven as stated by 

 Thorell, and the movable digit is nearly twice the length of 

 the hand-back (5|:3), whereas in the type of vittatus the 

 difference is much less, being only 5^ : 4. But without more 

 specimens for examination it is not possible to say whether a 

 specific or subspecific value is to be attached to these features.

Recorded from Barawain Somaliland; the British Museum 

 has recently received examples of apparently tiie same species 

 from Mombasa [D. J. Wilson) and East Africa [Imperial 

 British East Africa Company). According to Kraepelin this 

 species is identical with the foregoing U. vittatus, but the 

 three above-mentioned examples referred to Fischeri may be 

 distinguished from the Transvaal example of vittatus in the 

 features pointed out in the diagnosis. Kraepelin's description 

 is apparently based upon specimens from unstated localities, 

 one only being mentioned as coming from Somaliland, and 

 this is probably identical with Fischeri. According to this 

 author the variation in colour presented by the " species " is 

 very great, specimens even having the segments of the leo-s 

 ringed with black. The examples seen by me agree with 

 Karsch's description, except tliat they seem to approach my 

 example of U. vittatus more nearly in colour and have the hands 

 pale, whereas in the type of Fischeri these organs are said to 

 be marked with longitudinal blackish lines. The specimen 

 that I described as niyrimanus seems to represent a melanistic
