in an evenly rounded apex before reaching the distal margin. ‘The three lobes are 
connected with one another in the extreme anterior part of the telson and, in the larger 
specimen, the margins of the lateral pair are feebly corrugated. Along the lateral 
edge of the telson there is a prominent rounded ridge ; this ridge is continued to the 
outermost tooth on the distal margin, and is obliquely grooved in its posterior third. 
In the centre of the distal margin there is a deep and very narrow fissure extending 
half-way to the median boss, and on either side of this the edge is inflated and so forms 
a pair of obscure ridges. Three stout teeth, separated by triangular notches are found 
in each half of the posterior margin. ‘There are numerous submedian denticles and one 
on the inner aspect of each of the lateral teeth. 
The inner spine of the bifurcate process of the uropod is extremely small, not more 
than one quarter the length of the large and broad outer one. There are eight movable 
spines on the external aspect of the basal segment of the outer uropod. 
There can be little doubt that the two specimens on which the above description 
is based are correctly referred to Gonodactylus glaber. ‘They differ, however, from Lenz’s 
account in having the carapace and median rostral spine slightly longer proportionally. 
The keels on the lateral margins of the telson are not clearly shown in the original figure, 
and there is no mention’ of the proximal notch on the external margin of the raptorial 
dactylus. 
Spirit specimens are pale or brownish in colour with scattered black chromatophores 
which tend to form bands or patches in the posterior part of the carapace, on the sixth 
and seventh thoracic and on the first, fourth and fifth abdominal somites. 
The two examples of Gonodactylus glaber in the Indian Museum are registered

17. Gonodactylus tanensis (Fukuda). 
19tt. Protosquilla tanensis, Fukuda, Annot. Zool. Japon., VII, p. 285, pl. xi, figs. 1, 2. 
Of this species I have seen no specimens. It is, as Fukuda has remarked, closely 
allied to G. glaber, but may readily be distinguished from it by the sculpture of the 
last abdominal somite and telson. 
In addition to the usual prominences, the last abdominal somite is ‘‘ completely 
covered with irregularly-marked depressions.’’ The telson bears three bosses, 
situated much as in G. glaber, but with larger interspaces. These interspaces are 
covered with irregular depressions and in Fukuda’s figure look almost as if honey- 
combed. The median distal fissure and the lateral marginal lobes are nearly as in 
G. glaber and are provided with similar spinulation.
