Loe. Ceylon (frincomali, Kandy). 
The Museum has specimens of this species merely ticketed “Ceylon,” 
The only example with exact localities are an adult male anda young female 
from Kandy (Col. Yerbury), and an adult male from Trincomali (P. Bassett 
Smith). 
For the sake of comparison I append measurements}; of an adult female 
and male example of this species :— 
Q. Total length 46 ; length of carapace 24, width 20 ; length of first lee 
77, of second 67, of third 55, of fourth 67; patella and tibia of first 28 of 
fourth 23 ; protarsus of fourth 17, 
6. (from Kandy), Total length 35 ; length of carapace 16°5, width 13'8; 
length of first leg 66, of second 57, of third 47, of fourth 60, of palp 315 ; 
tibia of fourth 13°8 ; protarsus of fourth 16°5, of first 15, 
* In the above list no attempt has been made to give a complete quotation of the references 
to this spe-ies. The works that are cited are those that contain the original references to 
the name, those that contain figures of the species towhich the name “fasciata” haa been 
applied and those that ontain changesin the nomenclature of the genus. Nor must the 
inclusion of these references under one hearing be taken as evidence that I consider as 
cospecifie all the spiders that have been referre! to fasciata by the various authors cited 
above. They may all belong t» the same species, but the published figures and cescriptions 
are not safficiently accura'e and detailed to carry conviction on the point, 
+ In this and all cases the length of the legis taken from the base of the femur to the 
tip of the tarsal claws, and does not include the trochanter and coxa, 
The leg measurements must, however, in certain cases be used with caution, for, as 
compared with the carapace, these appendages are longer in smaller (younger) than in larger 
specimens; in other words, with increase of szethe carapace increases in length more 
rapidly than the legs. The total length in the table of measurements includes the carapace 
and abdomen, but not th> jaws (mandibles). The length of the abdomen, however, is of little 
importance, since in living specimens it varies greatly in size in accordance with the full- 
fed or fas ing condition of the spider, and in Museum specimens in accordance with the 
method of preservation whether in a dry state or in alcohol. Since the carapace is not 
subject to these alterations, ‘he !elative size of two spiders may be estimated by the length 
of this plate, which may be taken as the standard in Arachnoid mensuration,
