Mr. E. J. Miers on the Squillidae. 27 



those of the two following segments are broader and rounded 

 laterally, with a spinule at their postero-lateral angles. There 

 is a small median carinule or tubercle on the third to fifth post- 

 abdominal segments ; on the fourth and fifth segments the 

 lateral carinas, and on the sixth segment all the carinas end in 

 spinules ; the terminal segment is armed with a few tubercles 

 near its base, with a longitudinal median carina, on either 

 side of which is a lateral longitudinal series of very small 

 tubercles ; there is a rather deep median fissure between the 

 submedian mai'ginal spines, but no denticles ; between these 

 and the first lateral marginal spines there are on each side ten 

 or eleven very small denticles or spinules. The distal pro- 

 longation of the base of the uropoda ends in two very unequal 

 spines, the inner of which bears a small tooth on its outer 

 margin. Length of the larger individual about 5£ inches. 



Hah. Chili ; Auckland Islands. 



Two females are in the Museum collection, one of which 

 was taken from a bottle with obliterated label, the contents 

 of which were believed to have come from the west coast of 

 North America ; the other is from Laurie Harbour, Auckland 

 Islands (W. Wyheham Perry, Esq.). The former differs from 

 the Auckland specimen in having the rostral plate more nar- 

 rowed distally and armed with a terminal spinule, and in the 

 absence of punctulations on the terminal postabdominal seg- 

 ment. 



II. Penultimate joint of the large raptorial limbs armed with immobile 

 spines along its whole length.

Carapace elongated, with a longitudinal median ridge ter- 

 minating posteriorly immediately in front of the cervical 

 suture, and with two longitudinal lateral ridges on each side 

 between the cervical suture and the lateral margins, of 

 which the innermost is interrupted. There is a spine at the 

 antero-lateral angles, and at some distance in front of the 

 postero-lateral angles a strong triangular acute lobe or tooth ; 

 the rostral plate is elongated, narrowed, and subacute at its
