On South-African Talitride. 435 
LIII.—South-African Talitride. By the Rev. THomas 
R. R. Steppine, M.A., F.R.S. 
Wutte Dr. Chilton is reviewing the New Zealand members 
of this family, Mr. H. W. Bell-Marley is making interesting 
additions to the account given by Mr. Keppel Bernard of those 
which oceur in South Africa. The trustees of the Durban 
Museum desire to have the records of the local fauna printed 
as well as published in Natal. Owing to this not unnatural 
species of patriotism, a rather long interval cccurs before 
results arrived at in England can be passed through so 
distant a press. This may excuse the inconvenience of a 
brief preliminary notice for what I hold to be a new genus 
and species. At the end of October I received from Mr. Bell- 
Marley a number of ‘alitrid specimens, reddish-orange in 
colour as preserved, which he had found on Durban beach. 
He noticed that several were pairing, and the collection 
proved to have females, crowded with young ones, as well as 
males. After comparison of the latter sex with the synopses 
of the family drawn up in 1899 and 1906 and with subse- 
quent notices, it seemed clear that the species could not 
beiong to any of the known genera except /Zyalella. But 
when a female specimen was examined in ils turn, it showed 
a striking difference from all other species of that genus, 
numerous as they are. I therefore propose for these specimens 
Genus EXHYALELLA, nov. 
In general agreement with Hyalella, but having in the 
female the second gnathopod constructed like that of the 
male. 
Exhyalella natalensis, sp. n. 
The telson undivided, its distal margin not rounded, but 
obtuse-angled ; the third uropod with narrow ramus shorter 
than the peduncle. 
Full details and illustrative figures are reserved for future 
publication.
