MARINE BIOLOGY AT SCARBOROUGH. 



ARNOLD T. WATSON, F.L.S., 



Sheffield. 



Owing to the necessity of going to press somewhat earher 

 than usual, a number of specimens, mainly polychaste worms, 

 which turned up and were identified after the Meeting, were 

 unavoidably omitted from the hsts pubhshed in the December 

 number of ' The Naturalist.' In order that the Scarborough 

 record may be as complete as possible, it is desirable to give 

 the following supplementary list : — Aittolytus pictus Ehlers (rec.) ; 

 Syllis armillaris {loida) (rec.) ; Eulalia viridis Miiller (rec.) ; 

 Phyllodoce lamelligera Gmelin (rec.) ; Polydora ccBca Oersted 

 (rec.) ; Stylarioides {Trophonia) plumosa Miiller (rec.) ; Potam- 

 illa torelli Malmgren (rec.) ; Fabricia sabella 'Ehx. = Amphicora 

 fahricia (rec.) ; Polycirrns aurantiaciis Grube (rec). 



In addition to the above, an exceptionally interesting 

 Phyllodocid worm, most closely allied to a Canadian species of 

 Eteone, but possessing several special features of its own, was 

 found by Dr. Irving. This specimen has been forwarded to 

 Prof. Mcintosh, who has kindly undertaken to describe' it in 

 his ' Notes from the St. Andrew's Marine Laboratory, 'which 

 will in due time be published in the ' Annals and Magazine of 

 Natural History.' 



An addition to the List of Polyzoa has also to be made, as 

 I was fortunate in finding the interesting little eight-tentacled 

 species, Valkeria tremula, amongst my captives. 



It may, perhaps, be of interest also to add a few words 

 about the minute Gephyrean, Phascolosoma { = Petalo stoma) 

 miniitum Keferstein, to which reference is made at the close 

 of last month's report. 



This specimen was found embedded between the sand- 

 tubes built by the polychsete worm, Sahellaria spimdosa. It 

 is one of the smallest Gephyreans yet described, being only 

 about three-eighths of an inch long, and, though it has previous- 

 ly been recorded from the North Coast of France, Heligoland, 

 the Swedish Coast, and from Plymouth, it does not appear to 

 have been found elsewhere on the English or Scotch Coast. 



In 1908 a specimen of this worm came into the hands of 

 Mr. Rowland Southern, B.Sc. of Dublin, who described it in 

 the ' Irish Naturahst,' (Vol. XVIL, p. 171), as ' A New Irish 

 Gephryean.' He informs me that he has since found it in 

 considerable numbers at various parts of the Irish Coast, and 

 down to 500-600 fathoms. 



Since the Scarborough Meeting, nine other specimens have 

 been found there, probably, therefore, its escape from more 

 frequent observation is due to its diminutive size.* 



* Attention has been called to some misprints in the original \'ermes 

 List : Andonhiia should be Audoitinia, and Pomatoceras should read 

 Pomatoceros ; and PletiTobranchus pumilus should be P. plumulus.
