﻿MARINE ASELLOTE ISOPODS — MENZIES 



131 



Ecology. — This species appears to be a prominent member of the 

 Mytilus-Mltella biotope of exposed rocky coast localities. Ovigerous 

 specimens were found during May. 



Figure S3. — Munna chromatocephala, new species: a, First male pleopods; b, mature male 

 gnathopod; c, distal articles of seventh peraeopod; d, subadult male gnathopod; e, left 

 mandible;/, female operculum; g, distal portion of left mandible; h, distal joints of mandib- 

 ular palp. (Magnification as indicated by scales: / same as b; g and h same as d; c 

 unknown.) 



Remarks. — This species, although bearing a slight resemblance to 

 Mtmna suhneglecta Gurjanova (1936, pp. 254-255, abb. 3), can be 

 distinguished from that species readily by the fact that the tips of 

 the male first pleopods are considerably expanded laterally. In suh- 

 neglecta such tips are scarcely expanded laterally. The eyes of sub- 

 neglecta are on short but obvious stalks, which structures are almost 

 lacking in chromatocephala.
