species of Typhlotanais has been observed in the British seas, and that 

 this should be so is the more interesting from the fact that no fewer than 

 nine species are known to occur off the coast of Norway, but the majority 

 of them are small, and limited in their distribution to moderately deep 

 water, and this may account to some extent for their having escaped notice 

 hitherto. The length of Typhlotanais brevicornis is only about 1| mm. 



Paratanais batei, G. O. Sars. 



This species was collected by the " Garland " in Loch Etive in 9 fathoms, 

 off Abbot's Island, on March 30th. This is a new station for Paratanais 

 batei on the West Coast. 



Leptognathia breviremis (Lilljeborg). 



This was collected by the "Garland" off Aberdeen in 45 fathoms on 

 November 11th last year. 



Leptognathia brevimana (Lilljeborg). 



L. brevimana is a more slender species than the last, and is readily 

 distinguished by the structure of the uropods, the outer branches of 

 which appear to be but spiniform prolongations of the outer angles of the 

 basal joints. I have one or two records of this species for the Moray 

 Firth, where it has been taken by the " Garland," as well as off Aberdeen, 

 where it was collected in 45 fathoms along with the next form on 

 November 11th. 



Leptognathia (?) longiremis (Lillj.), var. (PI. XVIII. , figs. 30-38.) 



In the female of this Leptognathia the body is elongated and narrow, 

 being about seven times longer than broad (fig. 30). The terminal segment 

 of the metasome has no apparent denticle on its lateral margins as in 

 Leptognathia longiremis (Lilleborg). The antennules (superior antennae) 

 are moderately elongate^ being equal to about one-seventh of the length of 

 the body ; in the majority of the specimens examined the antennules were, 

 four-jointed (fig. 32), but, on the other hand, a number were observed 

 which had the antennules distinctly five-jointed (fig. 33), though in other 

 respects they appeared to be identical with those possessing the four- 

 jointed antennules. In the four-jointed antennules the first joint is 

 scarcely so long as the combined lengths of the next three joints, the 

 second and the last joints are nearly equal, while the third is only equal 

 to about half the length of the preceding joint. In the five-jointed 

 antennules the first joint is about twice as long as the second ; the 

 second, in its turn, is about the length of the third joint ; the fourth joint 

 is very small, while the end-joint is nearly as long as the entire length 

 of the third and fourth. 



The antennae (inferior antennas) are very similar to those of Lepto- 

 gnathia longiremis (Lillejborg), (fig. 35). 



The chelipeds (fig. 36) and the walking legs are very similar to the 

 same appendages in the female Leptognathia longiremis. 



The inner branches of the uropods, which are elongated, consist of two 

 sub-equal joints, but the outer branches, which are also two jointed, are 

 scarcely as long as the first joint of the inner branches (fig. 38). Length 

 of the female scarcely 2*5 mm. 



In the male the body is considerably shorter and broader than that of 

 the female (fig. 31). The antennules are proportionally longer than those 

 of the female ; the first two joints of the peduncle are dilated, but the
