once distinguished by having two secondary teeth below 

 the curved terminal nail of the third uropods, in which 

 respect it resembles P. falcatus, and by the distinct, 

 though small, secondary appendage of the upper antennae, 

 this in Janassa being so absolutely rudimentary that it is 

 only visible as a minute tubercle under a very high power — 

 say J in. obj. All the limbs are proportionally shorter 

 and stronger than in P. falcatus and the second joint of 

 the palp of the maxillipedes is more than half the length 

 of the first joint, while in P. falcatus it is less than half 

 the length. 



Podocerus ocius, Bate (female) — Delia Valle, Fauna des 

 Golfes v. Neapel — Gammarini. 



From sponge debris, Port Erin. Bate's figure appear 

 to have been taken from a female specimen ; the male is 

 figured by Delia Valle. It has two pointed teeth or 

 processes at the base of the palm in the second gnathopods 

 the proximal one being the longer. The outer ramus of 

 the third uropods has a curved but blunt nail and no 

 secondary teeth. Colour brown. Length of adult male 

 2J mm. 



Podocerus cumbrensis, Stebbing and Robertson (Trans. 

 Zool. Soc, Vol. XIII., p. 38, PL VI.), 



Bhos and Colwyn Bays ; Puffin Island ; Menai Straits. 

 Colour brown. Length 3 mm. Not uncommon in the 

 above localities. It has a strong superficial resemblance 

 to Microprotopus maculatus, with which I have generally 

 found it associated, and may easily be overlooked as being 

 the latter species. 



Janassa capillata (Eathke). 



Puffin Island ; Port Erin, breakwater, 2/8/94, common ; 

 5 m. W. of Dalby, 30 f., 8/7/94. This species may be 

 distinguished at a glance by the extreme hairiness of the 

 antennae ; the flagellum of the upper is three-jointed, the
