Hymenolepis [since identified as H. microps (Dies.) = H. tetraonis, 

 Wolffh.i] taken from a red grouse from the Pentlands, near Edin- 

 burgh. 



Drepanidotcenia gracilis. Zed. — Larva found encysted in speci- 

 men of the Ostracod, Candona rostrata, from Duddingston Loch 

 (T. Scott, Proc. Roy. Phys. Soc. Edin., x. p. 314, 1891). 



Davainea calva, Baird — Common in grouse. I have seen it at 

 Auchencorth Moss, in June, and have specimens from Cross wood 

 in April Dr Shipley tells me he has it from the Pentlands. [D. 

 urogalli (Modeer) is, it appears, an earlier name for this species.

Note. — I am not aware that any Mesozoa have been 

 detected here, but seeing several of the Cephalopods, etc., in 

 which they live are found in the Firth of Forth, a few may 

 reasonably be expected to occur. 



NEMEETINEA. 



Though studied, as to their habits and characters, by 

 Sir John Dalyell,^ and also to some extent by Harry 

 Groodsir,^ no one appears to have worked at the Nemertines 

 with the special object of ascertaining what species inhabit 

 the Firth of Forth. With the exception of two species of 

 MalacoMella, a genus then associated with the Leeches, they 

 are unrepresented in Leslie and Herdman's 1881 Catalogue 

 of the Invertebrates of the Firth. 



The giant of the group,^ Linens {G-ordins) marinus, Mont. 

 ( = Z. longissimus, Simm., and Nemertes horlasii, Cuv.) — the 

 Black Worm of the Newhaven fishermen — was well known to 

 Patrick iN'eill a century ago.^ In 1860 some specimens " of 

 enormous length " were procured in the Firth by the Com- 

 mittee of this Society on Marine Zoology ,6 It has since been 

 recorded by Dr T. Scott as comparatively common in the 

 Firth.''' I have found it several times at North Berwick in

^Professor M'Intosh says of a speciiaeu got at St Andrews in 1864: 

 "Thirty yards were measured without rupture, and yet the mass was not 

 half uncoiled" {Monog. Brit. Annelids, Part I.)
