A HISTORY OF LANCASHIRE 



BRACHIOPODA 



Only two species, Terebratula caput-serpentis, Linn., and Crania anomala, Mull., are known 

 from the Irish Sea. 



CRUSTACEA 



The Crustacea have received more attention than any other marine group. The number of 

 recorded species in the various sub-groups are: Brachyura, 28 ; Anomura, 13; Macrura, 23 ; 

 Schizopoda, 18 ; Cumacea, 20 ; Isopoda, 22; Amphipoda, 134. The Copepoda have received an 

 exceptional amount of attention ; about 260 species are now recorded, and of these nearly 50 are 

 parasitic forms inhabiting fishes. 



Cirripedia are represented by eleven species. Balanus balanoides, Linn., the common barnacle or 

 ' scab,' is, of course, the most abundant. At certain seasons in the year (March-April) the tow-nets 

 at Piel may contain 'practically nothing else than the nauplius larvae of these pests. The 

 extraordinary form Sacculina carcini is very abundant on the crabs captured off the mouth of the 

 Mersey. Peltogaster, a peculiar cirripede parasitic on the hermit crab, has also lately been recorded. 



Ostracoda are relatively abundant, about fifty species being recorded. 



PYCNOGONIDA 

 These are represented by twelve species. 



MOLLUSCA 



This group has naturally received very much attention ; 98 species of Lamellibranchia are 

 recorded, about 175 species of Gastropoda, 10 species of Chiton, 3 scaphopods ; Dentalium enta/e, 

 Linn., D. tarentinum, Lam., and Siphonodentalium lofotense, Sars. The cephalopods are Sepiola atlantica, 

 Lam., and S.scandica, Steenstrup, Rossia macrosoma,De\[e Chiaje, Loligo media, Linn., and L. forbesi, 

 Steenstrup, Sepia officinalis, Linn., and Eledone cirrosa, Lam. 



TUNICATA 



Fifty-four species in all have been recorded from the Irish Sea. Most of these have been 

 recorded from Puffin Island and Port Erin, and only four species are apparently recorded from the 

 Lancashire coast. But there is no doubt that this is far below the number that might be found if 

 looked for in suitable places.
