one observes a tubercle in the middle line and on either side of this tubercle a 

 transverse row of puncta; the last joint bears no tubercle. 



The thoracic legs resemble closely those of Scyll. sordidns, but the propodi of the 

 2nd jgCTs are in Stimpson's species a little slenderer. In the egg-bearing female of Scyll. 

 Martcnsii from Stat. 33 these joints are 3 mm. long and 0,95 mm. broad at the proximal 

 end of their upper margin ; in the j'ounger, egg-bearing female from the same locality they 

 are 2,14 mm. long and 0,58 mm. broad, appearing, in this younger individual, comparatively 

 broader. In the largest female of Scyll. sordidus, however, the propodus of the s'^'i legs is 

 4Y0 mm. long and i mm. broad at the base, in the other female from the same locality 3 mm. 

 long and 0,7 mm. broad. 



The abdominal appendages of the 2"'' somite of the larger male, long 31 mm. (outer 

 antennae included) from Stat. 164, are biramous, the rami being falcate with concave anterior 

 border; the longer ramus is slender, 3 mm. long, and 12-times as long as broad, ribbon-shaped, 

 tapering only near the extremity; the other is 2,8 mm. long, it gradually broadens until a little 

 beyond the middle, appearing here 0.54 mm. broad and 0,33 mm. at its base; at one-third 

 of its length from the extremity it suddenly narrows, appearing here only 0,27 mm. broad and 

 then it tapers regularly to the pointed extremity ; the posterior border of both rami is fringed 

 with long setae, the longer nearly along the whole length, the other only along the widened 

 middle part. The appendages of the 3''^ — 5"^ somites are biramous; the larger ramus is spoon- 

 shaped; that of the 3''' somite is 2,5 mm. long, the handle measuring 1 mm., a little less 

 than the spoon which is 0,9 mm. broad, with acute tip and with the margins fringed with 

 very short, plumose setae; the other ramus is very short, quite rudimentary and has the 

 form of a flowerbud, reaching as far as the jaroximal third part of the "handle" of the other ramus. 



The pleopods of the 2"'^ abdominal somite of the larger, ova-bearing female from Stat. 33 

 are biramous, the rami foliaceous, fringed with moderately long, ciliated setae; the somewhat 

 spoon-shaped endopodite, which is a little longer than the other ramus, carries a styliform, 

 internal appendix, 0,62 mm. long, 0,16 mm. thick, nearly 4-times as long as thick, with an 

 obtuse extremity, that is provided with long plain setae, measuring 2,4 mm. The appendages 

 of the 3 following somites are biramous and resemble those of Scyll. Haanii Berthold. 



Eggs very numerous, globular and small, presenting only a diameter of 0,36 mm. 



The other egg-bearing female from Stat. T^'i^ is 28 mm. long. The young male from 

 Stat. 64 measures 23 mm., outer antennae included. In the proximal (outer) squame of the 

 right external antenna the two posterior teeth on the outer border are not developed. The 

 female measures only 14 mm., outer antennae included. The two branches of the pleopods of 

 the 2"'' somite are still narrow, not broadened and their stylamblys is rudimentary; the slender 

 ramus of the following appendages is also rudimentary. The two males from Stat. 164 show 

 another coloration than the preceding specimens, but they belong certainly to the same species. 

 In both the 2°"^ tooth of the distal squame of the left antenna is doubled, so that there are 

 8 teeth instead of 7. 



One of the two females with eggs from Stat. 313 is 27 mm. long, outer antennae included. 

 The proximal (outer) squame ajjpears a little longer than usually and the distal squame of both
