Carida/rom the West Coast of Lvhuvl. 200 



^(jeon Breyidani*, sp. n. 



This species closely resembles A. cataphractu.i, from wliicii 

 it may be tlistin<i;uislK'tl by the S|»iiiiilatioii of the carapace 

 and telson and the shape of the anfceiinal scale. The whole 

 animal is, moreover, much more slender and the scul[)ture is 

 not so coarse. 



There are seven longitudinal carina?, represented by rows 

 of teeth, on the carapace ; the middle carina is straight, the 

 others more or less curved. There are four sharp teeth, 

 which point forwards, on the middle carina, the peimltimato 

 being the longest, 'i'he first lateral row bears six (rarely 

 seven) sharp teeth; the posterior four are not semiobsoh-te, 

 as is the case in cataphraclus. Tiie second lateral carina has 

 eight teeth, the five posterior being small and obscure ; and 

 the third lateral carina consists of twelve blunt spinules, 

 anterior to which is a sharp spine. 



The outer edge of the antennal scale is concave in Brendani, 

 whereas in cataphraclus it is convex, the wiiole scale being 

 more or less ovate. 



The telson is longer tlian the inner uropods and is dorsally 

 grooved ; it terminates in a very sharp point, on each side of 

 which in perfect specimens are three long setas. Two pairs 

 of dorsal spinules are also present on the telson. 



As in cata/'hractuSy the inferior extremities of the gills turn 

 forwards, and a small setose exopod is present at the base of 

 tlu' first pair of trunk-legs. 



The type specimen measures 32 mm. from the tip of the 

 eyes to the tip of the telson; the other six specimens are 

 between 23 and 30 mm. in length. All were caught by 

 trawling about 50 miles W. by N. of Inishtearaght Lighthouse, 

 Co. Kerry, in 320 to 370 fathoms. 



Lcontocaris^ lar, sp. n. 



Carapace furnished with a dorsal carina on its ant?rior 

 half, which is produced into three teeth, the anterior being 

 the largest and the posterior the smallest. 



The rostrum is longer than tlie carapace and reaches 

 filightly beyond the tips of the antennal scales; it is armed 

 above with ten long sharp teeth, which decrease regularly 

 in size from behind forwards.

 Ireland in the sixth century.
