CRUSTACEA OF NORTHUMBERLAND AND DURHAM 319 



Fam. 20.— AORID.E 



MiCRODEUTOPus ANOMALus (Rathke). 



I have the following notes; seven miles ofif Tynemouth, 25 

 fathoms, frequent; off Holy Island, 1864 (A. M. N.); Sunder- 

 land, low water (G. S. B.); but the only specimens now in my 

 collection are those from off Holy Island, which prove to be 

 females of Protomedeia fasciata (which see). This throws 

 some doubt on the other records. Females of the Aoridse 

 are often, especially young, difficult to distinguish ; but the 

 species last named is not likely to have occurred at low 

 water. Mr. Meek in his list gives *' Microdeutopiis sp., a 

 female was obtained at Cambois Bay in August, 1901."

Fam. 21.— PHOTID^ 



Protomedeia fasciata Kroyer. 



Off Alnmouth, 39-50 fathoms, and 16 miles ofif Souter 

 Point, 39 fathoms (A. Mk.). These specimens found by Mr. 

 Meek were very young; on re-examining three specimens which 

 were recorded in 1865 as ^^ Microdeiitopus anomalus^'' from ofif 

 Holy Island, 38-50 fathoms, I find them to be full grown 

 iexmXes oi Frofo?nedeia fasciata. A character which was the 

 first to catch my eye, and is a very distinctive one, was the 

 very slender propodos of the anterior pairs of peraeopoda, and 

 the slenderness and great length of the nail, which is quite as
