310 Mr H. D. S. Goodsir on two New Spec ics of Leachia. 



This species resembles L. lacertosa^ but its prominent parts 

 are more boldly thrown out. The plates on each side of the 

 antennae do not project, and their inferior-anterior angles 

 are acute. The superior antenna) are longer than the two first 

 joints of the inferior ; the first joint is globose, the second, 

 third, and fourth are slender, and the fifth is globular. The 

 inferior antennae are almost as long as the body ; the first joint 

 in each is as long as the head, cylindric, and having a ridge 

 on its external side ; the following joints are more slender, 

 and the last joint finely pointed. A double row of tubercles 

 run down each side of the body immediately above the inser- 

 tion of the legs. They are large and very prominent on the 

 three anterior and three posterior articulations of the thorax, 

 but on the fourth articulation they are not so prominent, and 

 are placed in a regular series on each side of the longitudinal 

 hinges peculiar to this segment. The abdomen bulges consi- 

 derably, and then tapers suddenly to a point at its posterior 

 extremity. The animal is of a straw colour spotted with 

 brown. 



Hab. Firth of Forth, off Anstruther. 



2. Z. gracilis. (Mihi.) 



L. gracilis. Antennis superioribus pauUo brevioribus, tribus priniis 

 articulis inferiorum ; quarto thoracico segmento, lineari-cylindricoj et 

 non tuberculato. Long-, lin. 7. 



In this species the body is very slender and quite smooth, 

 without the tubercles which are found in all the other species. 

 The plate which covers the base of the antennsQ projects, and 

 is rounded anteriorly. The superior antennae are almost as 

 long as the three first joints of the inferior. The first joint 

 globular, the second and third linear, each of them as long as 

 the first, the fourth equal in length or longer than the others 

 conjoined, and the fifth is minute and linear. The inferior 

 antennae are as long as the body. The first joint obsolete, the 

 second slightly clavate, and the last three joints strongly pec- 

 tinated on their inferior edges. Both pairs of antennae have 

 a few bristles scattered over them. The body is quite smooth, 

 with the exception of a few scattered punctures. The fourth 

 thoracic segment is linear, cylindric, and not tuberculated.
