[Echinoderma — eo7itd. ] 



Solasteridse. 



SoLASTER PAPPOSUS (Fabricius): L\ Forbes, Hist. Brit. Starf., p. 112, fig. 



Fairly common on coarse sand and gravel, 15-35 fms. (s.P.) : the 



most plentiful starfish in 1892 (w.g.): Mewstone Gds., Rame- 



Eddystone Gds. (r.a.t., S.P.) : Eddystone Gds. (E.J.A., s.P.): Stoke 



Pt. Gds. (s.P.) : Cattewater, probably from trawl refuse (r.a.t., S.P.). 



Gonads ripe in Mar. (t.y.ii.). 



Echinasteridae. 



Heneicia sanguinolenta (0. F. Mliller) : K Forbes, Hist. Brit. Starf., 

 p. 100, fig. (as Cribclla oculata). 



Eeny Eks., occasional specs, at extreme low water (r.a.t.) : not 

 uncommon on the Mewstone Gds. (r.a.t., s.p.) : Eddystone Gds., 

 occasionally on clean medium gravel (e.j.a., s.p.) : Stoke Pt. 

 Gds. (s.p.). 



Asteriidae. 



Asterias glacialis, Linnffius : H. Ludwig, Fauna Flora Neapel, vol. 

 xxiv, p. 364, fig. 



More or less common at all stations below low- water mark, but 

 somewhat uncertain in its occurrence (s.p.) : large specs, generally 

 from deeper water, 30 fms. and over (e.j.a.) : the Breakwater, not 

 uncommon ; Yealm E., not uncommon in dredgings, large specs, 

 occasionally on the Sand-bank (r.a.t.) : Eddystone Gds., most 

 abundant where Pcdcii opcrcularU is plentiful (e.j.a.). 



Asterias rubens, Linnaeus : E. Forbes, Hist. Brit. Starf., p. 83, fig. (as 

 Urastcr). 



Occurs below tide-marks at most stations, but in very varying 

 abundance in difterent years; it is generally plentiful, but occasionally 

 it would seem to be almost absent:* a smaller, violet-coloured var. 

 is met with on coarse ground in 15-30 fms. (e.j.a., s.p.). 



Ophiolepidae. 



Ophiura albida, Forbes: F. J. BcII, Catal. Brit. Echinod. Brit. Mus., 

 p. 108. 



Lives generally on coarser soil and is less abundant than 0. cilia ris 

 (e.j.a.): Mewstone Gds. (r.a.t.): Stoke Pt. Gds., fairly common; 

 Eame-Eddystone Gds. (s.p.) : Eddystone Gds. (e.j.a., s.p.). 



Ophiura ciliaris (Linmeus): F. J. Bell, Catal. Brit. Echinod. Brit. Mus., 

 p. 106. 



Common, 15-35 fms., on gravel and sand (s.p.) : most frequent 

 on fine hard sand (e.j.a.) : Mewstone Gds. (R.A.T., s.p.) : Stoke Pt. 

 Gds. (s.P.): Eame-Eddystone Gds. (e.j.a., R.A.T., S.P.): Eddystone Gds. 

 (e.j.a., s.p.) : Looe-Eddystone Gds. (S.P.). 



Breeding: May (r.a.t.): Aug. (s.P.). 



* Not a single spec, of A. rubens was obtainable from towards the end of Oct. 1903 until 

 well on in the spring of 1904, although repeated search was made for it both in the Sound 

 and in Cawsaud H. (s. i'.).
