Report on a collection of Loricata from Manora Island, Karachi, with descriptions of three new species and a new variety
In June 1951 Dr. A. R. Ranjha of the Zoological Survey Department, Government of Pakistan, at Karachi, sent me 26 samples of Loricata, together 46 specimens, preserved in 75% rectified spirit, all, except one, from the rockey beach of Manora Island, about two miles West off the Karachi coast, where they had been collected from the tidal area at low tide. The samples were taken at different dates and by several collectors or collecting parties. There are four species and one variety among the material, of which three species and the variety are supposed to be new. Chiton iatricus Winckworth, 1930 Winckworth, R., 1930.
