PLATYMOPS HAAGNERI spec. nov. 
A small species having an affinity to P. petrophilus in the dental 
formula, flattened skull, absence of a definite antitragus, shortness and 
number of the bristles on the toes, and in the horny points on the 
upper part of the ears being situated near the horizon of the ear ; but 
differing therefrom in its smaller size, the horny points on the ears only 
two in number ; the lower P2 much smaller than the P4, which is higher, 
the tips of M lt P 4 and C forming an almost straight line at a slight 
angle rising forward ; the upper incisors are also comparatively shorter 
than in petrophilus , and a cingulum can be seen in P2 with the aid of 
a lens. The lower incisors are bifid. The bony palate extends well 
behind the molars. 
Dimensions of the type in spirits: Length of the head and body 50 
mm.; of the tail 32, of the free portion of the tail 13.5; ear, height 10, 
breadth 13.5; height of the tragus 2.3; length of forearm 37; pollex 
(c.u.) 5; third digit, metacarpal 37, 1st phalanx 14, 2nd without carti- 
lage 12; fourth digit, metacarpal 36, 1st phalanx 12.5, 2nd phalanx 
without cartilage 6; fifth digit, metacarpal 25, 1st phalanx 10, 2nd 4.7; 
tibia 10; hind foot, length (c.u.) 6.5 Skull: Greatest basal length 16.2; 
zygomatic width 10 ; width at mastoid 9.8 ; width of brain case 9 ; in- 
terorbital constriction 3.7; basilar length 13.1; palate length 5.5; length 
of dental series, from front of C to back of M3, 6 ; width of palate taken 
outside the molars 7 ; greatest length of mandible 12. 
Type: Adult male from Keetmanshoop, Damaraland, presented to 
the Museum by Mr. Sigmund Haagner. 
These two species apparently belong to the genus Platymops Thos., 
but differing as they do in the dental formula, the P 2 being present, 
I propose to place them in a new subgenus bearing the name of 
SAUROMYS, of which P.haagneri maybe taken as the genotype. The fol- 
lowing figures will indicate the difference in the height of the skull of 
N. aegyptiacus and the present new species, the measurements having 
been taken from the tips of the P 4 vertically parallel to the top of the 
premaxilla : 
N. aegyptiacus 6.5 mm., P. petrophilus 4.2, P. haagneri 4. 
GEORYCHUS PALKI spec. nov. 
Most closely allied to G. anomalus mihi in having the nasals long 
and narrow and the same buffish grey coloration ; but differing from 
this and all other members of this group in having a very distinct semi- 
circular notch in the upper anterior angle of the ocular area of the skull, 
this notch effecting a thinning of the arch of the maxilla above the 
antorbital foramen and opposite the antorbital process. In two adult 
specimens the hindmost molar is very large, equal in diametre to the 
foremost tooth. 
Dimensions: Length of the head and body 150 mm.; tail 22; hind
