VII. FurRTHER NOTES ON HIPPOLYTIDAE. 
By StaNLeEyY Kemp, b.A., Superintendent, Zoological Survey 
of India. 
(Plate XXXVI). 
Although only two years have elapsed since my previous paper 
on the Indian Hippolytidae was published, a number of interest 
ing forms have come to light, obtained partly during the recent 
cruises of the ‘Investigator’ by Capt. R. B. Seymour Sewell, 
I.M.S., partly by Dr. Annandale in Japan, and partly by myself 
during a short visit to Port Blair in the Andamans. 
The Hippolytid fauna of Port Blair is one of great richness. 
During three weeks’ collecting, fully half the known Indian species 
of the family were met with, enabling me to obtain notes on the 
natural colouration of several forms hitherto unknown in this 
respect. In addition, three forms were found that had not pre- 
viously been recognised, one representing a new generic type. 
_ Of these, Thor discosomatis is of particular interest owing to the 
fact that it lives commensally with a large anemone of the genus 
Discosoma, and is most peculiar in its colouration ; the species of 
Phycocaris, gen. nov., is extremely grotesque in appearance and 
closely mimics the weed among which it lives. 
Borradaile, in a recent paper,! has briefly described a genus 
and three new species of Hippolytidae from the Maldives, the 
Seychelles and other localities. If my identification is correct, 
two of these, Thor maldivensis and Lysmatella prima (the latter 
the type of the new genus), occur in the Andamans; but I am 
inclined to think that Lysmatella should at most be distinguished 
only subgenerically from the closely allied Hzppolysmata. Ex- 
hippolysmata, recently proposed by Stebbing’” to include Hzppolys- 
mata ensirostris and a nearly related form from S. Africa, does not 
appear to differ sufficiently to warrant either generic or subgeneric 
separation.
