Distribution. 

 Genus recorded from S.W. Atlantic. 



Genus recorded from "W. Indies and 

 Tasmania. 



The genus is specially characteristic 

 of the tropical Pacific, but extends 

 to Puget Sound and Japan . It also 

 occurs in the tropical Atlantic, in 

 the Mediterranean and S. African 

 waters. 



Perhaps identical with a Polynesian 

 form. 



The genus has much the same dis- 

 tribution as Chromodoris. 



Closely allied to B. fiilva from 

 California and perhaps identical. 



The same species is recorded from 

 the N . Atlantic and Mediterranean. 

 The genus is also represented in 

 the Indian Ocean. 



The genus is also recorded from 

 the N. and S. Atlantic, the 

 Mediterranean, and Japan. 



The species is recorded from the 

 N. Atlantic and N. Pacific. The 

 genus is characteristic of the 

 colder seas, and is not recorded 

 from the tropics. 



29. Tritofiia inccrta, Bergh 



. . . Nearly allied to A . meiulifera from 

 Tasmania or identical. 



... Genus probably cosmopolitan, but 

 specially frequent in colder seas. 



It would appear from the above list that the nudibranch fauna of 

 E'ew Zealand contains at least three elements. (1) A tropical element, 

 represented by such genera as Chromodoris and Doridopsis, which are 

 particularly abundant in the Equatorial Indo-Pacific. (2) Forms 

 which are characteristic of the colder seas. In some cases, such as 

 Archidoris, these genera appear to be cosmopolitan, though they are 

 more noticeable in colder waters ; in others, such a?. Acanthodoris, they 

 are not recorded at all from the tropics, but are abundant in temperate 

 climates both to the north and south. The close agreement in species 

 is very remarkable. Goniodoris castanea is found in the North 

 Atlantic, Mediterranean, and New Zealand seas. The distribution of 

 Acanthodoris pilosa has already been mentioned. In a list of New 

 Zealand Nudibranchs kindly sent me by Mr. Suter is Archidoris 

 tuberculata. I have not seen myself specimens of this form from the 

 Southern seas, but Vayssiere (Exped. Antarct. Francjaise, Moll. Nudib., 

 1906, p. 4), records it from Wandel Island. It is found in the North 

 Atlantic, Mediterranean, and N. Pacific. It is noticeable that forms
