Sub-family VIII. Lecithasterinae Odhner 1905. 
Genus i. Lecithaster Liihe 1901. 
Species 1. Lecithaster gibbosus (Rud.) 1802. 
This species was comparatively frequent. It was met with in the 
intestine of Trigla pini, Gobius ruthensparri, Labrus berggylta, Gadus 
merlangus and Drepanopsetta platessoides. With the exception of 
Gadus merlangus all these species are new British hosts of the parasite. 
In its wide distribution and in the fact that few specimens occur in each 
host, it resembles Derogenes various , but the numbers which occur are 
even much less than in the case of the latter species. In most of its 
hosts only a stray specimen occurs, but in Gadus merlangus quite a large 
infection may be met with. In Drepanopsetta platessoides also I found 
nearly a dozen specimens but they were all immature. 
For a description see Odhner (1902), Lebour (1908), and Nicoll 
(1909 b). 
Sub-family IX. Sterrhurinae Looss 1907. 
Genus i. Lecithochirium Liihe 1901. 
Species 1 . Lecithochirium rufoviride (Rud.) 1819. 
This species is confined to the conger-eel, in practically every 
specimen of which it is to be found. It is a stomach parasite and occurs 
in enormous numbers. It has already been recorded from Millport by 
Elmhirst and Martin (1910). 
It is a well-known species and has been frequently described, most 
recently by Johnstone (1907, pp. 177—180, as Distomum ocreatum Molin) 
and Looss (1908, pp. 144—147). 
Sub-family X. (Dinurinae Looss 1907.) 
Genus i. Lecithocladium Liihe 1901. 
Species 1. Lecithocladium excisum (Rud.) 1819. 
This species also is confined to one host, Scomber scombrus, in the 
stomach of which it is frequently found, although never in such large 
numbers as is the case with the preceding species. The two are rather 
like each other in size, shape and colour but their internal structure 
is greatly different. 
The last description is that b}' Looss (190S, pp. 131—2).
