4.22 Mr. Hugh Scott on a large series of 
de Meij., the property of the Cambridge Museum, which 
were obtained by the Skeat expedition to the Malay 
Peninsula, and determined by Dr. Speiser. I owe my 
best thanks to Professor Poulton for kindly lending the 
type of C. sykest from the Oxford Museum. 
A close comparison of the Ceylon female specimens with 
Westwood’s type has left no doubt that they are C. sykesz. 
(The male sex was described by Westwood (op. cit.) as a 
separate species, C. hopei.) They are distinctly larger and 
darker than the type; the latter has the long bristles on 
the end of the abdomen conspicuously reddish, whereas in 
the Ceylon specimens these are more fuscous. Neverthe- 
less, investigation has revealed no clear character separating 
the Ceylon females from the type of C. sykesi. It must be 
mentioned, too, that all the Ceylon specimens are pre- 
served in spirit, while the type is in a dried condition. 
Though the species 1s not new, a description of the Ceylon 
series may not be out of place. 
FEMALE.—Dark reddish-brown ; cox somewhat lighter ; femora 
much lighter, testaceous, except at the apices, where they are dark ; 
the three cross-furrows of the tibia lie in its proximal portion. 
Head bearing short bristles, palps with long bristles. Thorax 
dorsally greyish-white at the sides ; the central part darker. Under- 
side of the thorax covered with short, not very strong, bristles. 
Basal abdominal segment. Dorsal plate with its extreme base 
whitish and bearing a group of very short black bristles ; remainder 
of the plate dark red-brown, more anteriorly without bristles, the 
posterior portion with 3 or more irregular rows of rudimentary 
dark bristles at some distance from one another; hind margin of 
the plate with + 6 conspicuous moderately long bristles, on either 
side of the body, at the lateral angle. Ventral plate with a few 
rudimentary bristles at its extreme base; posterior to these, 3 
irregular rows of short dark bristles (the bristles become longer 
towards the hind margin of the segment); margin of the plate 
bearing the characteristic ctenidium of strong black teeth. 
Penultimate abdominal segment. Whitish, covered with black 
tubercles (“Dornenrudimenten”). On the ventral and_ lateral 
surfaces these tubercules bear short bristles. The mid-ventral part 
of the hind border of the segment bears + 7 long bristles. On the 
dorsal surface, the tubercles of the anterior two-thirds bear only 
exceedingly minute rudimentary bristles ; in the middle is a bare 
space, having a group of much larger tubercles, of the number of 
which I shall speak later ; on the posterior one-third the tubercles
