392 Miscellaneous. 



P. notigera, Stal (Brazil), is only known to me by the 

 description ; it is probably a true Pyg Idler ana. 



P. caffra, Dohrn, and P. dcemeli, Dohrn, are only known to 

 me by their description and by drawings ; the position 

 which I have allotted them by analogy may well be 

 correct. 



P. ahnormis, Borm., is the type of Tomopyjia, Burr (1904). 



P. biittneri, Karsch, is the type of Karschiella, Verhoeff.

Contrihut'ions towards a Revision of the Genus Lomanotus : 

 a Postscript. 



1 REGRET to find that the survey of the literature of the genus 

 Lomanotus given in the paper which appeared under the above title 

 in the August issue of these ' Annals ' is incomplete, in so far as it 

 includes no reference to Sir C. Eliot's vakiable " Notes on some 

 Lritish Nudibranchs," contributed to vol. iii. of the ' Journal of the 

 Marine Biological Association ' in 190G. Unfortunately the exist- 

 ence of these " Notes " did not come to my knowledge until some 

 three weeks after the appearance of the August issue of the 

 ' Annals.' Having read the section of the " Notes " dealing with 

 Lomanotus (pp. 348-353) I find it necessary to alter my views as to 

 the position of L. portlandicus. Hancock's unpublished drawings 

 show that this species possesses what appears to be the most 

 important specific character of Trinchese's L. eisigii, a fin-like cairdal 

 process, so that the two species may be considered as identical. 

 While still retaining two species in the genus, I desire, then, to alter 

 the arrangement proposed in the August number of the ' Annals ' 

 (pp. 217-218) to the following, L. portlandicus (1860) taking 

 precedence of L. eisigii (1883) : — 



(1) L. marmoratus, Aid. & Hanc. (1845). 



L. gcnei, Verany (1846). 



L. hancocki, Korinan (1877). 



(2) L. portlandicus, Thompson (1860). 



L. eisigii, Trincbese (1883). 



Whether this provisional arrangement is to stand will depend on 

 the value that may be conceded as a specific distinction to the 

 fin-like caudal process of the second species as described by 

 Trincbese and figured by Hancock. N. Colgan.
