* LEPiDONOTas CLAVA, Montagu. 



This species is very common, but by no means so abundant as the 

 last, and is more restricted in its distribution. It occurs below tide- 

 marks, but between them it is most numerous at extreme low water 

 under stones. All authors seem to agree in limiting the size of this 

 species to something like an inch and a half, but local specimens of 

 such a size would be regarded as small. They frequently occur up to 

 2| inches, and sometimes even more. Under these circumstances the 

 elytra are widely separated, and a very good figure of the worm in this 

 condition is given by Bourne (4). Pruvot (29) records it from the 

 higher strata of tidal waters among fucus-covered rocks in the Channel, 

 and from the same zone in the Golfe du Lion in the Mediterranean.

f Lepidonotds pleiolepis, V. Marenzeller. 



The species described under this name is recorded from the Japanese 

 seas, and is characterised by the possession of 15 elytra, a fact which 

 should lead to a modification of the genus. St.-Joseph describes a 

 specimen from Ct^zembre, which he assigns to this species. As it only 

 possesses 12 elytra and is very small, he somewhat apologetically 

 explains that it is only a young one.

* Malmgrenia castanea, Mcintosh. 



By no means uncommon. This species has, in this locality at least, 

 only been found as a commensal on the under surface near the mouth of 

 Spatangus purpureus, and is therefore found on the same kind of ground 

 as that frequented by the echinoderm.
