ends of which latter is somewhat less than that between the epibranchial angles. The hind 

 margin of the carapace is straight and only 'j., of the distance between the anterior anorles. 



The abdomen, as Koelbel remarks, is almost wholl)' similar to that of Scopiinera globosa 

 (fig. 2 f), but the fourth segment has less produced anterior angles and is about as lono- as 

 the preceding segment; the fifth segment is narrower at the base, not longer than the next, 

 and the terminal segment is not semicircular, but semi-elliptical. It is curious to note, that in 

 the type species, T. pn'silliis, the abdomen of the cT is of the ordinary shape, and is not 

 constricted at all in the middle. 



The infra-orbital border projects much forward beyond the supra-orbital one and presents 

 a number of remarkable features, the principal one being that is divided into two parts, which 

 induced Koelbel to make this species the type of a new subgenus, which he called Tiiicihy- 

 i)ocoeiis. The inner part is the longest, twice as long as the outer part, concave in front view, 

 and straight, somewhat sloping in dorsal view ; it is somewhat granular, the granules alternating 

 with very short hairs, that resemble those on the lateral border of the epibranchial angle, and 

 is separated from the outer part of the border by a very deep notch, resembling that between 

 the external orbital angle and the epibranchial tooth. The outer part of the border is more 

 sloping and meets the carapace at. the level of the epibranchial tooth (so that the external 

 orbital angle is wholly free at its under surface), but before joining the carapace it is deeply 

 concave; this outer part of the border is ornamented in the same way as the inner part. As 

 to the latter is must be added, that immediately below the border, at the ventral wall of the 

 orbit a row of granules, parallel with the border itself, is running, and that somewhat lower 

 (in upper view apparently parallel to the inner part of the border, but in reality straightly) a 

 row of long hairs is found, running from the base of the eye-stalk to near the deep notch 

 dividing the infra-orbital border; these hairs increase in length towards the outward and the 

 terminal hairs are directed dorsally. 



The side walls of the body are perpendicular in the fore parts, but somewhat sloping 

 outward at the subbranchial regions; they are everywhere covered with setiferous tubercles. 

 Pterygostomial regions not longitudinally grooved and not defined from the subhepatical regions, 

 that again pass imperceptibly into the subbranchial parts; these latter are faintly divided into 

 two parts by a somewhat raised rim, running obliquely from the epibranchial tooth to the base 

 of the penultimate leg, but gradually disappearing in the terminal half, as Koelbel already 

 mentions, but the development of this rim seems to vary individually. 



The eye-stalks are widening somewhat distally and the cornea, that does not exactly 

 reach as far as the external orbital angle, is bulging. The eye- stalk is 'continued 

 beyond the cornea and projects as a cylindrical horn considerably beyond 

 the eye, as this horn is -j„ of the length of the eye-stalk itself; the end is provided with 

 some short, stiff hairs, disposed in single file, but deciduous (according to Koelbel). This 

 remarkable feature of the species, that makes it look like Ocypoda ceratoph- 

 thalina (Pallas), distinguishes it at once among all other species of this and 

 the next s u b f a m i 1 y. 



The lateral margins of the buccal frame are somewhat concave, accompanied by a sulcus
