are transverse and a little oblique ; and the eye-peduncles, 

 whict are somewliat thickened at the cornea, are as long as the 

 orbits. The upper margin of the orbits, which is finely ciliated, is 

 smooth, entire, and a little raised upward, and the external angle 

 is obtuse and not prominent. The lateral margins of the upper 

 surface are slightly divergent posteriorly, and terminate nearly 

 between the bases of the fourth and fifth pair of legs, being 

 somewhat deflexed downward ; their anterior half appears rather 

 concave and their posterior slightly convex ; so that the greatest 

 width of the upper surface is found behind the middle. The 

 lateral margins are slightly raised upwards along their anterior 

 half, and present a small emargination immediately behind the 

 obtuse external orbital angle, without forming, however, an epi- 

 brauchial tooth. The lateral margins are shortly ciliated. The 

 external antennae are short, scarcely reaching to the cornea of the 

 eye-peduncles. The inferior margin of the orbits is smooth and 

 entire, and terminates laterally in a triangular, obtuse, thickened, 

 much prominent lobe, which constitutes the external angle of the 

 infraorbital margin. In those species of the genus Dotilla that 

 I have examined, such as de Haan's Scopimera glohosa, this lobe 

 is quite absent, the external angle of the infraorbital margin 

 being not at all prominent ; and this difierent structure of the 

 orbits changes so much the general outer physiognomy of this 

 species, that I was induced by it to regard this form as the repre- 

 sentative of a new genus. The short ciliated external margin of 

 the orbits, which unites the external angles of the supraorbital and 

 infraorbital margins, presents a triangular hiatus close to the 

 external angle of the supraorbital margin. The pterygostomian 

 regions and the other inflected sides of the cephalothorax are 

 smooth, not sulcate, and rather thinly covered with short hairs ; as 

 in the genera Gelasimus and Kelcecius, a ciliated line is found on 

 the lateral surface of the cephalothorax, proceeding from the 

 middle of the lateral margins towards the bases of the legs of the 

 penultimate pair. The smooth, short, and narrow epistome is 

 slightly more prominent than the front. The anterior margin of 

 the buccal cavity presents a triaHgular equilateral prominence in the 

 middle as ini)o^i7Z«, and a small narrow incision ateach lateral angle. 

 The external maxillipeds closely resemble those of the genus 

 Dotilla ; but their merus-joints are quite smooth and ungrooved. 

 They meet along their inner margins, which are a little hairy. 

 The ischium-joint is quadrangular, scarcely broader than long ;
