The first peraeopods have the third joint produced into a tooth. 



The second perseopod on the left side has the fifth joint (the 

 carpus) divided into twenty compartments. That on the right 

 side also appears to agree with Professor Smith's reckoning, accord- 

 ing to which it should have twenty-three compartments. The 

 fingers of the fourth and fifth peraeopods are cleft, but the divisions 

 seem to be of equal length and closely contiguous. 



The branchiae agree with the formula given by Smith and 

 Alcock for Glyphocrangon. 



The specimen specially examined for this description measured 

 75 mm. in length. It contained the Bopyrid Bathygyge grand-is, 

 Hansen, on the right side of the carapace. Another specimen 

 was of just the same length. A third was 77'5 mm. long. A 

 fourth was smaller than the other three. These four were dredged 

 at the same station, Cape Point N.E. by E. % E. 40 miles ; depth 

 800-900 fathoms ; bottom, green mud. A specimen 88 mm. long 

 was obtained at about 800 fathoms depth, Cape Point N. 70 E. 

 40 miles. At each of two other stations, but at the same locality 

 and depth as the station first mentioned, a single specimen was 

 obtained, each measuring 75 mm. in length.

Eyes long retaining a purple hue. Between this and the pre- 

 ceding species there are two tolerably clear distinguishing features. 

 Behind the large antennal and antero-lateral spines, the carina 

 ends in a single anterior tooth, the after part having no further 

 dentation. The side-plate of the fifth pleon segment has its lower 

 margin cut only into two teeth, not three. What may be the true 

 systematic value of these two characters remains somewhat un- 

 certain. In his later account of the species Professor Smith says, 

 when speaking of the teeth or spines on the lower margin of the 

 pleon segments, " there is usually no posterior spine on the fifth." 

 As apparently he had only four specimens in all, it may be surmised 

 that one out of the four had a posterior or third tooth on the fifth 

 pleon segment. The proximal division of the median carina of
