Stat. 88. June 20. o°34'.6N., U9°S'.sE. Northern part of the Strait of Makassar. 1301 m. 

 Bottom fine grey mud. Trawl chiefly brought up yellow mud. One full-grown 

 egg-bearing female. 



Carapace and rostrum of this beautiful, well preserved specimen are together 66 mm. 

 long, the abdomen 85 mm., so that this female is 151 mm. long, 30 mm. longer than the 

 specimens obtained by the "Challenger"; the rostrum, 27 mm., measures almost three-fourths 

 the length of the rest of the carapace, the distance between the tips of the foremost teeth of 

 the 4 th or lateral carinae measures 31 mm., the distance, finally, between the anterior extremities 

 of the posterior moieties of the 3 ld or dorso-lateral crests 30,5 mm. In the "Challenger" type 

 rostrum and carapace together were 49 mm. long, the abdomen 72 mm., so that in the full- 

 grown female from Stat. 88 the abdomen appears a little short er in proportion to the 

 rest of the body than in the younger Challenger type. 



Though this female should in my opinion be referred to Bate's species, it shows some 

 differences both from the description and the figures. The two flattened spines, into which the 

 anterior moiety of the 4 th or lateral crest is cut, are less pointed, less acuminate than 

 in Fig. 1 of Bate's Report, while the notch between them is deeper. In that figure the anterior 

 parts of the dorsal ridges of the carapace appear to be formed by 11 or 12 sharp narrow 

 cusps or teeth, while in the female from the Strait of Makassar one observes only 5 or 6 

 laterally compressed and rather obtuse cusps, like in Glyph. priononota; behind the cervical 

 groove the dorsal ridges are formed by 5 or 6 cusps, that decrease in size backward. The 

 rostrum is armed on each side with two spines, the anterior reaching just beyond the eye, the 

 posterior situated just behind it, but there is no third small spine at the base of the rostrum, 

 as described by Bate in his female. The anterior moiety of the 2 nd or subdorsal crest is 

 represented by three or four teeth, like in Glyph. priononota, of which the anterior is by far 

 the largest and larger than the rostral spines, being almost of the same size as the anterior 

 tooth of the 4 th or lateral carina : in Bate's figure, however, one observes behind the large 

 anterior tooth still 5 or 6 smaller ones. The posterior moiety of the subdorsal crest is formed 

 in the female from Stat. 88 by 5 or 6 obtuse and compressed teeth, of which the anterior but 

 one is longer than the rest, in Bate's figure, however, by 8 sharp teeth, that increase in size 

 backwards. The only present posterior moiety of the 3 rd or dorso-lateral crest ends anteriorly 

 in a subacute tooth, while its posterior half shows two or three notches, by which three teeth 

 or tubercles are formed, the anterior of which is longer than the posterior. For the rest the 

 carapace is covered, between the carinae, with an equally large number of granules or teeth 

 as in the Challenger type, with a larger number therefore than in Glyph. priononota, but these 

 granules are obtuse or subacute and they show, especially on the cardiac and branchial regions, 

 a tendency to fall into lines parallel with the crests. There are 25 or 26 subacute granules of 

 unequal size on the hepatic region and 4 granules are observed on the orbital region between 

 the rostrum and the orbital spine.
