314 CRUSTACEA OF NORTHUMBERLAND AND DURHAM 



Apherusa Jurinii (H. Milne-Edwards). 



This is Ainphithoe norvegica Rathke and Phenisa fucicola 

 Bate partly (see Walker, Ann. and Mag. Nat. Hist., May, 

 1891, p. 418). 



CuUercoats (J. Alder) ; 5-6 miles off Souter Point, 30 

 fathoms (A, Mk.);. four miles off Tynemouth in 27 fathoms 

 (G. S. B.) N.D. 



Calliopius Rathkei (Zaddach). 



Common between tidemarks. N.D. 



Calliopius l^viusculus (Kroyer). 



Occasionally taken between tidemarks. We cannot regard 

 the last as distinct from the present species (A. M. N.) N.D. 



Fam. 16.— ATYLID^ 



NoTOTROPis SwAMMERDAMii (H. Mllne-Edwards). 



Abundant between tidemarks. N.D. 



NoTOTROPis FALCATUS (Metzgcr). 



Alnmouth, 1899 (G. S. B.) ; not uncommon on the sand 

 outside of the rocks at CuUercoats and Druridge Bay (A. Mk.) 



Mr. Meek makes the following interesting statement, " The 

 modified first pair of perjeopoda are used to grasp fragments 

 of shell. Most frequently two pieces of shell are taken and 

 grasped by the modified appendages. The animal has then 

 the appearance of lying in a bivalve shell — the fragments of 

 shell coming pretty close together dorsally. The active 

 movements of the apparent bivalves betray, however, their 

 crustacean occupant to the observer." N. 



NoTOTROPis vEDLOMENSis (Bate). 



Near Holy Island, 35-50 fathoms ; 40-50 miles E. by N. 

 from Tynemouth, 40 fathoms (A. M. N.). Two miles off 

 CuUercoats (A. Mk.); off Souter Point, 1904 (G. S. B.) N.D. 



Fam. 17.— DEXA.MINID^ 



Dexamine spinosa (Montagu). 



This species seems to be rare on the east coast, while it is 

 common on all the other shores of Great Britain.
