rather longer than the telson, the outer and longer ramus showing a 
faint dizresis. 
The length of the carapace is 12 mm., of the pleon about 23 mm., 
including 5 mm. for the telson. Mr. Bell Marley reports the colour 
in life as ‘“ goldeny-brown on white with irregular lines and curves, 
antenne red, legs brown and white.” 
Locality: Isezela.

Kemp, whose valuable treatise supplies other references, incidentally 
remarks that ‘‘ Filhol’s Hippolyte spinifrons, as is shown by the figure, 
is undoubtedly synonymous with White’s Alope palpalis ; he refers to 
the supra-orbital spines as ‘épines sus-orbitaires’ following Milne- 
Edwards’ mistake in terminology.” It is true that in the description 
of H. spinifrons by Milne Edwards (Hist. Nat. Crust., vol. ii, p. 377) 
we find printed ‘‘épines suborbitaires.” But undoubtedly it was the 
printer and not Milne Edwards who made the mistake, which Filhol 
corrects instead of following, since the prefix ‘“‘sus” signifies supra 
not swb. Thomson also, it will be seen (loc. cit., p. 445) misconstrues 
Filhol. In the two species of the genus now accepted, A. palpalis, 
White, and A. australis, Baker, the latter author supposes the first 
maxille to differ in a marked but very improbable manner. He has 
evidently been led to this conclusion by the circumstance that 
according to Thomson’s figure and description the first maxilla of 
A. palpalis is devoid of the customary inner plate. It is, I think, 
practically certain that the supposed loss is due to an accident in 
dissection.
