REPORT OF SECTION FQR MARINE ZOOLOGY. 



Although this section has not jet existed two years, 

 I am glad to say that it has made substantial progress. On 

 the systematic side of the work Mr. E. D. Marquand, 

 A.L.S., reports as follows : — 



There is probably no one living at the present time who 

 possesses such a profound critical knowledge of the British 

 Marine Mollusca as Mr. J. T. Marshall, and certainly no 

 one who knows so much about the shells of the Channel 

 Islands. I had the pleasure last summer of spending many 

 delightful hours in Mr. Marshall's company, during his stay 

 of a few weeks in Guernsey. He very kindly looked through 

 my wife's collections of marine shells from Guernsey and 

 Alderney, and his sharp eye detected several forms which 

 w r e had overlooked or confused with others, and which 

 consequently were omitted from my two published lists. 

 This enables me to add the following novelties for the two 

 islands, a few of the forms being new to the Sarnian area : — 



Modiolaria marmorata, Forb. Alderney, in corallines between tide-marks. 



M. COStulata, Riss. Bordeaux, Guernsey, one valve (Mrs. Marquand). 



Loripes laeteus, L. Two valves, Braye Bay, Alderney. 



LueinopsiS undata, Perm. Alderney, one valve. 



Saxieava rugosa, var. prcecisa, Mont. Bordeaux, Guernsey (Mrs. 



Marquand). 

 Teredo megOtara, San. Abundant in a log of wood washed ashore 



in Alderney in 1902. Erroneously recorded last year as Xylophaga 



LittOPina rudiS, var. saxatilis, Mont. A very dwarf nearly black form 

 occurs in abundance in Lichina at high water mark in Guernsey and 

 Alderney. Becorded by error as Assiminea littorina. 



RiSSOa eingillus, Mont. Two specimens of a deep purple colour, without 

 the usual bands, were found alive in Alderney by Mrs. Marquand, among 

 var. rupestris. Mr. Marshall, who identified them, said he had never seen 

 such a form before. 



OdOStomia riSSOides, var. glabrata, F. & H. Alderney. 



0. pallida, var. angusta, Jeff. Alderney. 



0. unidentata, Mont. Alderney, one dead specimen. 



0. Warreni, Thomp. One specimen in Alderney shellsand. 



Nassa pygmaea, Lam. Guernsey (Marshall). Alderney, dead in shell- 

 sand (Marquand). 



Defraneia reticulata, Ren. Two worn specimens in Alderney shellsand. 



Pleurotoma rufa, var. lactea, Jeff., Alderney. Var. prcelonga, Marsh. 

 Shell beach, Alderney, with var. semicostata. 



In Mr. J. W. Taylor's splendid monograph of the Land 

 and FreshilWater Mollusca of the British Isles, now publishing 

 in parts (which, I am glad to know, is subscribed for by 

 the Guille-Alles Library) a few slugs are recorded for our
