brief and imperfect that it is impossible to decide how closely related these two are. They 

 may be the same species, but so far as the description shows, it is quite possible that the 

 resemblance is a superficial one only, and that they are not at all similar in their essential 

 characteristics.

In his description of this species, which is very brief, he does not say whether the 

 sixth abdominal somite is fused with the telson. It is possible that it is not related in 

 any way to the species of Protosquilla, but I place it here provisionally as the only 

 points he mentions show a striking likeness to Protosquilla cerebralis, with which it 

 may possibly be identical. 



His short notice simply says that it is like Gonodactylus trispinosus, but that the 

 tei-minal post-abdominal somite is ornamented with two oval tubercles, bounded by an 

 impressed inverted line, and with a medium cinquefoil-shaped one, and the two preced- 

 ing segments symmetrically engraved with fine lines.

Diagnosis. — Protosquilla mth eyes slightly enlarged at tips, carapace as wide as 

 long. Second thoracic somite exposed. First five abdominal somites with marginal 

 carinse. Fifth abdominal somite with several transverse rows of short acute dorsal spines 

 on its posterior half. Sixth abdominal somite covered on its dorsal surface with 

 numerous long spines. Posterior edge of telson with two paii-s of marginal spines pro- 

 jecting backwards. The submedian with a single row of secondary spines on each side, 

 and the laterals with a singrle row on the inner and a double row on the outer edge, 

 running from its tip along the outer edge of the telson to its anterior end. Dorsal 

 surface of telson with twenty-two long spines symmetrically arranged. Second 

 joint of exopodite of uropod nearly three times as long as paddle. Dilated base of 

 dactylus of raptorial claw truncated on its outer edge, and not notched. Endopodite of 

 uropod with five spines on its dorsal surface.
