with, the last ; it is a rare form, and has not hitherto been observed on the 

 south side of the Forth. Laophonte denticornis differs from L. serrata, 

 Glaus, in having the outer branches of the first thoracic feet three- 

 jointed, and in the different form of the fifth feet in both the male and 

 female ; the female also wants the posterior dorsal spine which is 

 characteristic of the female of L. serrata. Laophonte hispida and 

 thoracica were also obtained in this Musselburgh gathering.

This species, which is not difficult to identify, even without dissection, 

 by the peculiar form of the fifth thoracic feet in the female, was 

 moderately frequent in the gathering from the old quarry at Granton in 

 which Stephos scotti was obtained.

Description of the Female. — Body elongated, narrow, cylindrical ; all 

 the segments distinct except the first and second of the abdomen, which 

 are slightly coalescent. The first three segments of the abdomen have 

 their lateral angles produced into small spiniform processes. Rostrum 

 short and broadly triangular. Caudal joints narrow and elongated and 

 equal to nearly one and a half times the length of the last abdominal 

 segment (fig. 20). 



The antennules are short and stout and composed of five (or six) joints ; 

 the end joint is narrower and rather longer than the others, while the 

 penultimate one is very small; the last four joints are also all setiferous, 

 as shown by the drawing (fig. 21). 



Antennae two-jointed and of moderate length; the end joint is pro- 

 vided with spiniform, marginal and terminal, setae ; a few of the terminal 

 setae are elongated, but the others are moderately short. The secondary 

 branches of the antennas are rudimentary, and are represented by a single 

 short hair as in Cletodes limicola, G. S. Brady (fig. 23). 



The mandibles are stout, elongated, sub-cylindrical, and armed with a 

 few stout apical teeth. The palp is composed of a single one-jointed 

 branch, and is provided with several plumose setae (fig. 24). 



The second maxillipeds are composed cf two moderately slender joints, 

 and the terminal claw is also slender and elongated (fig. 25). 



The first pair of thoracic feet (fig. 26) resemble in their structure and 

 armature the first pair in Cletodes limicola ; both branches are short, but 

 the three- jointed outer branches are rather longer than the two- jointed 

 inner ones. In the inner branches the end joint is narrower and about 

 one and a half times longer than the other. Moreover, the seta on the 

 outer angle as well as the one on the inner angle of the second basal joint 

 are both elongated, the inner one being also plumose. In the second pair 

 (ijg. 27) the outer branches are elongated and slender, but the inner two- 

 jointed branches are short; the second joint of the inner branches is 

 narrow, and fully twice as long as the first joint ; two very long hairs 

 spring from its truncate apex, but otherwise it is unarmed ; the outer 

 branches are provided with long slender spines on the exterior distal 

 angles of all the three joints ; there is also a single slender seta on the
