pairs of peraeopods agrees with the figures given of /. Ehlatur, 

 but not with the same parts in /. minuta, the last perseopod 

 of which is figured separately by iSars, though (for once as 

 regards Sars) it is not quite satisfactory; the true form of the 

 coxa of that leg will be seen better represented in his entire 

 figure of the animal. Again, Stebbing's drawing represents 

 projecting angles in the middle of the sides of the first two 

 segments of the metasome; such projections are characteristic 

 of /. Eblance, but are not present in 1. minuta, though in one 

 of our Norwegian specimens of that species we see a very 

 slight tendency towards such projections in the shape of a 

 backward curve of the margin at the same part. In the 

 points to which attention has been directed, Stebbing's 

 I pi d media approaches much more nearly to /. Eblance than 

 to 1. minuta. But in /. Eblance, " the three anterior seg- 

 ments of the pleon are each armed with a well-developed 

 tooth in the median dorsal line; " and Bate, in his original 

 description of the species (Nat. Hist. Review, vol. iv. 1859, 

 p. 229, pi. xvi. fig. 1), prints the foregoing words in italics ; 

 and further on speaks of the character as " that which most 

 strongly strikes the notice." With these marked differences 

 from both described forms, we feel it necessary to leave the 

 question of Stebbing's IpldniaJia as a matter to be determined 

 by future investigations ; but it is certainly the same species 

 as that described and figured from the Mediterranean by 

 Delia Valle under the name Iphimediopsis Ehhuia 1 (Delia 

 Valle, p. 586, pi. vi. fig. 5, pi. xxxii. figs. 1-19, pi. Iviii. 

 fig. 93).

PEREIONOTUS TESTUDO (Montagu). 



1899. Pereionotus testndo, Norman, " Notes on Montagu's Hunting- 

 ground, Salcoiube Bay," Ann. & Mag. Nat. Hist. ser. 7, vol. iv. 

 p. 288, pi. v. figs. 1, 1 (and synonyms). 



In the paper just referred to, Norman announced the 

 rediscovery after sixty-five years of a single specimen of this 

 species of Montagu in Salcombe Bay, where the type specimen 

 had been found : in a subsequent visit in 1903 he procured 

 another specimen in the same spot. Though well known as 

 a Mediterranean species, it has not as yet been found in any 

 second habitat in our seas.
