the anterior margin, propodos long, dactylos small, transverse ; second 

 pair similar in form, but very long and slender. Pereiopoda as in P. sjnnosa, 

 but with the margins of the squamiform plates smooth. Telson rounded at 

 the extremity. Colour uniformly Hght brown (when examined under a low 

 power of the microscope the whole body is seen to be dotted with reddish- 

 brown star-like marks). Length 0-35 inch.

" The cephalon is produced in advance, more like a hood than a rostrum. 

 The superior antennae are situated considerably in advance of the inferior. 

 The integumentary structure is generally thin and semi-transparent ; and I 

 am inclined to think that most of the genera are burrowers, for which pur- 

 pose the hood-like cephalon affords an efficient protection. The three 

 posterior pairs of pleopoda are double-branched." 



Genus Amphilochus, Spence Bate. 

 (Brit. Mus. Cat., p. 107.) 



Cephalon anteriorly depressed. Eyes two, posterior to the superior 

 antennae. Superior antenna without an appendage. Gnathopoda sub- 

 chelate ; in both pairs the carpus is produced along the inferior margm of 

 the propodos. Pereiopoda subequal ; cox^e of the third pair not so deep as 

 the preceding. Telson single.

 nous, not clawed.)

Fig. 5a & B. 



Body broad and thick anteriorly, slender posteriorly. When seen under 

 a medium power of the microscope the integument — which is very thin — is 

 seen to be covered with minute scale-like marks and spiues, hence the 

 specific name. The cephalon (fig. 5a) is depressed anteriorly between the 

 bases of the superior antennse. Eyes large, deep red in colour, but not easily 

 made out owing to the numerous and dense reddish-black spots with which 

 the greater part of the body is coloured. Superior antennse shorter than 

 inferior; peduncle shorter than flagellum, which is seven -jointed and carries 

 two long setae at the extremity of each joint. (The last joint of the peduncle 

 bears a minute one-jointed appendage.) Inferior antennse not one-fourth 

 as long as body ; flagellum slender, longer than the peduncle, smooth. 

 Gnathopoda (fig. 5b) subequal and similar in form ; meros and carpus pro- 

 duced into obtuse lobes, which are spinous at the extremity ; propodos with a 

 rounded palm, and a few spines at the point of impingement of the slender, 

 falcate dactylos. Pereiopoda slender and subequal. Ante-penultimate 

 pleopoda reaching almost to the extremity of the ultimate, smooth ; penulti-
