174 Annals of the South African Muse inn. 



Moreover, although Walker states that his species closely resembles 

 N. vedlomensis (Bate and Westw.), he does not specifically mention 

 the branchial lamellae. The South African specimen is indistinguish- 

 able from vedlomensis except in respect to this latter point : the 

 branchial lamellae namely are pleated. I rather suspect that a 

 re-examination of Ceylon specimens of gramdosa would reveal the 

 presence of pleated lamellae and confirm the specific identity of the 

 Ceylon and Natal specimens and their distinctness from the European 

 vedlomensis.
