AMPHIPODA AND ECHINODERMATA FROM THE RUNA. 



had identified and which he afterwards sent to me for incorporation in this- 

 paper. It is as follows : — 



^Aristias nec/lectus, Hansen. 



Perrierella Audoniniana (Sp. Bate). 



Tryphosa Sarsii (Bonnier). 



Am2)elisca temticornis, Lillj. 



„ spimjjes, Boeck (young). 



Haijloops tubicola, Tjillj. 



Ainphilochus mamidens, Sp. Bate. 



Leucotlio'e spinicarpa (Abildg.). 



Cressa dubia, Sp. Bate. 



Ste)wtho'e marina (Sp. Bate). 



Coloniastix jMsilla, Grube. 

 *Panoplcea Eblance (Sp. Bate). 



Neopleustes bicusjm (Kroyer). 



^Sipnp)leustes latipes (M. Sars). 



Epimeria cornUjera (Fabr.). 



Melita obtusafa (Montagu). 



Maera Othonis (M. -Edwards). 

 ^Photis Iteinhardi, Kr. 



Eurystheus maculatus (Johnston). 



Leptoclieirus pectinatus (Norman). 

 [? = Z. pilosus^ Zadd.] f 



Jassa pusilla (G. 0. Sars). 



Erichtlionitis brasilie7isk (Dana). 



Proto 2>edata (Mliller). 



Astacilla longicornis (Sowerby). 



Janira maculosa, Leach. 



The four species marked with a star have not been found by us in the- 

 Irish Sea area. 



This is probably the most northerly record of Colomast'uv pusilla, Grube.- 

 It was found on the ( 'Cylon Pearl Banks in 1902 (see Herdman's Report, 

 Royal Society, Part 11. p. 299). 



Panojyloea Ehlana' (Sp. Bate) is a Mediterranean species. The most 

 northerly record hitherto is that of the type described by Spence Bate from 

 specimens taken from the branchial cavities of Rliizostoma from Dublin 

 Bay. It appears to be very rare in British seas, as it does not even occur in 

 the magnificent collection presented to the British Museum by Canon A. M. 

 Gorman, as I am informed by Dr. Caiman, who identified this species. 



Mr. H. C. Chadwick, A.L.S., has identified the Echinodermata of the 

 cruise as follows : — 



Holotharia tremula, Gunner. 

 Phyllophorus Drummo7idi (Thumps. 

 Antedon Milleii (Wyv. Thom.). 



„ phahmgiwn (J. Miill.). 



„ bifida (Penn.). 

 Luidia ciliaris (PhiJ.). 



,, Sarsi, Diib, & Kor. 

 Palmipes placenta (^Penn.). 

 Solaster pap)p)osus, Fabr. 



„ endeca, Linn. 

 Asterias Murrayi, Bell. 



Asterias Muelhri (Sars). 



,, nd^ens, Linn. 

 Porania pulvillus (O. F. Miill.}. 

 Ophiuva ciliaris (Linn.). 



„ albidu, Furb. 

 Amphiuva CJiiajii, Forb. 

 OpJiiopholis aculeata (Linn.). 

 Asteronyx Love^ii, M. & T. 

 Spatanyus pwpureus, O. F. Miill, 

 BrisKojJsis lyrifera, Forb. 

 Echinus esculentus (Linn.). 



The Hebridean specimens of Echinus esculentvs, compared with those 

 commonly found at the Isle of Man, are uniformly higher and more 

 pentagonal in shape, and have the primary tubercles on both ambulacral and 

 interambulacral plates smaller in size and number, and the secondary 

 tubercles much more feebly developed. The arrangement of the pores on- 

 the ambulacral plates is also slightly different in the tAvo cases. 



+ These two are considered distinct by Mrs. Sexton (Proc. Zool. Soc. Lond. 1911, p. 561)
