I. — A new Species o/Munna /rom New Zealand. 

 By Charles Chilton, M.A., B.Sc. 



[Plates I. & II.] 



The genus Munna was established in 1839 by Kroyer; but 

 as yet only a comparatively small number of species appear 

 to be known. Beddard, writing in 1886, says that only five 

 species were then known, all of them being inhabitants of the 

 shallow water off the coasts of Great Britain, Norway, North 

 America, &c.^ He adds two species, M. maculata and M. 

 2)aUida, both obtained from shallow water off Kerguelen Land 

 during the ' Challenger ' Expedition. Each of his species is 

 remarkable for some point : M. pallida has the eyes without 

 the appreciable stalks found in other species^ and in J/, macu- 

 lata the male has the same form of body as the female and is 

 not narrowed and elongated as in some of the other species 

 of the genus. 



I am now able to add another species, found between tide- 

 marks on the coasts of New Zealand. As in M. maculata^ 

 the male has the same form of body as the female ; the species 

 appears to differ from the others hitherto described in having 

 the first pair of thoracic appendages of the male very large
