varied. The Comatulce are pretty generally distributed in 

 Rocquaine Bay, where they are accompanied by Asterias 

 glacialisj Ophiothrix fragilis^ and Asteriscus. Gucumaria 

 2)entactes and C frondosa also exist in Rocquaine Bay ; but 

 1 have only found the Sea-Urchins in the north of the island. 

 One day I met with a small Echinocardium cordatum, Penn., 

 in the neighbourhood of the Port, close to the Chateau Cornet j 

 it is the only specimen of the species that I have found at the 

 English islands. Lastly, in the produce of a dredging I 

 observed fragments of Luidia fragilissima^ Forbes. Tliis 

 interesting species seems to be tolerably abundant in the 

 neighbourhood of Guernsey. A person who collects Actiniae 

 for the English aquaria showed me an entire specimen, which 

 was found one day to the north of Bordeaux at low water. 

 The fact deserves to be recorded, as the Luidia appears to 

 be a rather rare form. 



Vermes. 



A list of the Vermes of Guernsey was published in 1866 by 

 Ray Lankester in the Ann. & Mag. Nat. Hist. (vol. xvii. p. 388). 

 I havefoundthegreaterpartof the species indicated by tliat natu- 

 ralist, at least of the Polych^ta, but I have captured a certain 

 number of forms which he does not record. Of the Turbel- 

 larians I have only met with a few species, which, moreover, 

 also live at Jersey. I will indicate : — Leptoplana tremellaris^ 

 common everywhere ; Prosthecerceus vittatus, which lives in 

 the Zos^e/-a-meadows (Belgrave Bay, Lihou ; the Guernsey 

 specimens are larger than those of Jersey) ; Proceros argus^ 

 Quatref. (Grand Havre) ; Polycelis loivigatus (Rocquaine Bay) ; 

 and Eurylepta cornuta (Bordeaux, Grand Havre). Lineus 

 longissimus is very common at Bordeaux ; it is also met with 

 at Cobo, at Lihou, and near the Port, under stones. Nemertes 

 gracilis and Tetrastemma candidam also are not rare. The 

 three Jersey species of Valencia are found in the mud covered 

 with Zosterce^ where they are associated with Marjjh/jsce and 

 Clymenians. 



The Polychseta are very abundant. The Amphinomians 

 are rej^resented by Polgnoe squamata, P. cirrata^ and Sthene' 

 lais Edwardsiij common at Bordeaux, Grand Havre, and 

 Rocquaine Bay. Lankester also cites Harmothoe sarniensisj 

 which I have not met with ; as to H. Ilalmgreni, Lank., 

 which, as is known, lives as a commensal in the tubes of the 

 Chcetopterij I have found it also in Guernsey in the tubes of 

 Choitopteri from the port of St. Pierre.
