NUDIBRANCHS FROM THE COAST OF NATAL. 



221 



On Some Nudibranchs from the Coast of Natal. 



By 

 Sir Chai-lcs Eliot, K.C'.J^I.G. 



A SMALL collection of Nudibranchs made by Mi\ Buniup in 

 Natal, and kindly submitted by liim to me for examination, 

 contains the following" five species : 



No. of 



Name. 

 Marionia arbor esc ens 



Discodoris coerulescens 

 Thordisa burnupi n. sp. 

 Chromodoris porcata 

 Chroinodoris carnea 



specimens. 

 . 4 . 



Previous records. 



Amboina, Philippines, 

 East Equatorial 

 Africa, Red Sea. 



Mauritius. 



Mauritius. 



Mauritius. 



Another small collection made by him on the same coast 

 consisted of Chromodoris runcinata, Chr. annulata, 

 Chr. lineata, Chromodoridella mirabilis, and Hexa- 

 branchus adamsii (see Eliot in ' Proc. Mai. Soc.,' vi, 1905, 

 pp. 232-6). Thus of ten species from Natal eight belong- to 

 the Indo-Pacific fauna, and the two neAv species are not 

 incongruous with it. It would seem that in the southern 

 portion of the East African coast the Nudibranchs are much 

 the same as those found near the Equator, as well as on the 

 shores of Mauritius and Madagascar. Bergh's account of 

 the Opisthobranchiata of South Africa (in 'Trans. S. Afr. 

 Phil. Soc.,' xvii, 1907) confirms this to some extent, as the 

 collection which he examined included such Indo-Pacific forms 

 as Chromodoris, Doridopsis, Kalinga, Nembrotha,
