This species is very closely allied to S. guinquedentata but may be distinguished 
by the following characters :-— 
1. The rostrum is distinctly longer and its upturned lateral margins are rather 
more strongly convergent. 
2. The eyes are larger, the breadth of the cornea is about one quarter the length 
of the carapace and the corneal and peduncular axes are strongly oblique 
(fig. 42). 
. The antennular peduncle is a little longer than the carapace excluding the 
rostrum. 
4. The outer inferior margin of the merus of the raptorial claw is not produced 
as a spine ; the external margin of the dactylus shows only the very feeblest 
traces of sinuation (fig. 43). 
. The lateral lobes of the sixth thoracic somite are about equal in length ; the 
anterior one is apically truncate and is not very much narrower than the 
posterior which terminates acutely. Both lobes of the seventh somite are 
acute, the anterior being more than half the length of the posterior (fig. 42). 
6. There are more spines on the abdominal somites. The following carinae 
end in spines :—

In respect of the punctuation and carination of the carapace and abdomen and 
in the number of teeth on the raptorial dactylus, this species bears the closest resem- 
blance to S. guinguedentata and, like it, possesses a three-segmented mandibular palp. 
The telson (fig. 44) also is closely similar, but the marginal teeth are longer and 
the outermost submedian denticle is often distinctly larger than any of the rest. The 
lobe on the outer aspect of the longer spine of the uropodal process is rather unusually 
prominent. There are three or four submedian denticles, six or seven intermediate 
and one lateral. 
Though so nearly allied to S. guinquedentata, there is, I believe, no doubt that S. 
gonypetes is a distinct species. ‘The greater obliquity of the corneal portion of the eyes 
and the different form of the lobes on the margins of the thoracic somites are charac- 
ters which preclude the suggestion that the specimens are merely young examples of 
the form described by Brooks. ! 
' Among the species belonging to the S. oratoria group it is noticeable that in very young specimens
