included A. crypt opy gins Ortmann 1891, A. latipes (Cole) 1906, A. arenicola 
(Do lira) 1881, A. abyssi Sars 1891 (A. tridens Meinert 1899), A. eastelli 
(Dohrn) 1881. 
The only other representative of the genus so far obtained from Torres 
Strait is A. tenuicdllis Carpenter 1892, collected by Dr. ITaddon. This agrees 
with A. melwardi in the general slenderness of the body, but differs in the 
absence of the high dorsal trunk processes, in the form of the ocular tubercle, 
in the form and proportions of the proboscis, in the presence of a rudimentary 
chela, and in many other points. 
In the absence of any trace of tin 1 chela A. melwardi apparently differs 
from all previously described species of the genus. 
Genus NYMPIIOPSIS Haswell, 1884. 
Nymphopsis armatus Haswell, 1884. 
Specimen . — One specimen, female (.juv.), Australian Museum, Reg. No. 
Locality .- — Dredged in 9 fathoms near Lindeman Island, Whitsunday 
Figure 4 . — Nymphopsis armatus Haswell. Lateral view of trunk with legs and ovigers 
omitted. 
Remarks . — The holotype of Haswell \s species is preserved in the 
Australian Museum as a microscope slide (U 5:201). Loman (1928, p. 41) has 
suggested that A. korotnewi Sehimk., 1887, may be synonymous with A. armatus 
Haswell. 
Comparison of the specimen collected by Mr. Ward with the type shows 
that some important features have been overlooked in my previous revision of 
the description of the holotype (1919). There are in the holotype between the 
ocular tubercle and the abdomen t wo dorsal trunk elevations seen with difficulty 
in the holotype slide. They are to be well seen in the specimen from Whitsunday 
Passage. Such elevations are to he found now in all species of the genus except 
A. korotnewi Sehimk. In A. armatus, however, the elevations are of very 
moderate height as compared with other species. Another point is that the 
abdomen bears two pairs of pinnate spines instead of one pair as stated in my 
former description. The second pair is situated on the same face of the abdomen 
somewhat lower down.
