 Polycheles baccata C. Sp. Bate, Report on the Challenger Macrura, 1888, p. 131, PI. XIV, Fig. 1. 



Stat. 38. April 1. 7°35'.4S., U7°28'.6E. 730—915 m. Bottom: coral. 1 male and 1 female 



without eggs. 

 Stat. 297. January 27, 1900. lO°39'S., I23°40'E. 520 m. Bottom soft, grey mud with brown 



upper layer. 1 very young specimen, 23 mm. long, without legs of the ist pair, 



probably belonging to this species. 



The two specimens from Stat. 38, which are of equal size, do not fully agree with Bate's 

 description and show especially some differences from his figure, but this figure 1 of Plate XIV 

 is certainly inaccurate. When being in London some time ago, I was enabled to examine the 

 Challenger types: the dorsal ridge, which was described as being "without teeth or spines", 

 proved, however, to be spin ulo se and granular, but the small spines were here and 

 there worn off and less distinct than in the specimens from Stat. 38. 



As is proved by comparing the measurements, this species closely resembles in its outer 

 appearance Pol. typhlops Heller. The proportions between the length, the greatest width of 

 the carapace and the distance between its anterodateral angles are indeed quite the same. The 

 carapace, not yet one and a half as long in the middle as measures its greatest width, appears 

 very slightly convex transversely, except, like in other species, on the flattened hepatic regions. 

 Beneath the hairy tomentum, the upper surface of the carapace is beset with small, sharp 

 granules. The concave frontal border ends on each side into a strong and acute, flattened 

 tooth, at the inner angle of the orbital notches, and between these teeth that are directed 

 almost horizontally forward and the pair of juxtaposed rostral spines that are directed upward 

 and slightly forward, the frontal border appears somewhat spinulose in the male and slightly 

 granular in the female. The median, conical tooth that arises on the frontal wall of the carapace 

 immediately below the rostral spines and that is directed upward and slightly forward, is v e r y 

 large and reaches considerably beyond the rostral spines; in the male it is rather acute, in 

 the female obtusely pointed. The finely granular, median ridge on the gastric region carries 

 two small acute teeth standing side by side immediately behind the middle; between this pair 

 and the two rostral spines one observes in the male five, in the female four, single, acute teeth 

 about of the same size, placed behind one another and between this pair and the cervical 

 groove the ridge widens a little and is here beset with irregularly arranged, small, acute teeth
