the description is again generic, not specific, and as I have no 
specimens before me from these islands I cannot add to it. 
P. nigrimanus (Koch) is from India. It is probably the species 
common in the Eastern Ghats, as has already been suggested by 
Hansen.! ‘This is the only species known to me of which (spirit) 
specimens ever seem to resemble Koch’s figure in colour. 
P. deflersi (Simon) may be distinguished by the presence, even 
in large specimens such as the type of the species, of two well de- 
veloped spines on the dorsal margin of the hand, as in the genus 
Damon. Both these spines are, however, present in the young of 
certain other species. 
P. jayakari, Pocock, differs from all other known species in 
the presence of a pair of stout spines on the margin of the carapace 
in front of the lateral eyes. 
P. phipsoni, Pocock, is a distinct species, apparently confined 
to the northern parts of the Western Ghats. 
P. pusillus, Pocock, is a common Ceylonese form, allied to 
but distinct from P. ceylonicus (Koch) of which it may conve- 
niently be regarded as a variety. It is much smaller than this or 
any other species of the genus known to me. 
Phrynichus scullyi, Purcell, from S. Africa® is probably des. 
cribed from immature specimens, but as I have not seen any I 
cannot speak with certainty. 
P. bacillifer (Gerst.) remains, of course, distinct. 
The determinable species of the genus may be recognized 
thus :— 
Margin of carapace without strong spines 3 2. 
Margin of carapace with a pair of strong for- 
wardly directed tooth-like aoe in front of 
lateral eyes aS: .. P.sgayakert, p. 455. 
One spine only present on upper waren, of hand 
of adult «.:; 3: 
Vertical basal spine as well as oblique spine distal 
to it persistent on upper margin of hand in adult P. deflersi, p. 455. 
i 
Anterior surface of femur of arm with 3-5 sharp 
spines, or simply granular; lower margin al- 
ways with some sharp spines 4. 
Anterior surface of femur of arm with 2 or 3 blunt 
rounded bacilliform processes in the basal ‘third ; 
lower margin spineless P. bacillifer, p. 455: 
A longitudinal row of granules present on lower 
surface of hand (pl. xxxi, fig. 14) P. ceylonicus, p. 449. 
Lower surface of hand smooth (pl. xxxi, fig. 13). 5: 
Tibia of arm of adult with two long terminal 
dorsal spines preceded only bya minute tuber- 
cle * ; basal dorsal spine of hand absent in adult, 
small or absent in young P. nigvimanus, p.453: 
Tibia of arm of adult with the two long terminal 
dorsal spines preceded by a short but well 
developed spine; basal dorsal spine of hand 
probably always well developed in young, re- 
presented by a tubercle in adult .,, 6.

® This tubercle replaces a spine which is present in the young of this as of 
other species,
