Mr. E. J. Miers on the Squillidae. Ill 



lateral angles. Terminal segment with an acute median 

 longitudinal carina (but without lateral carinules or tubercles), 

 with eight lateral marginal teeth, the one next the submedian 

 teeth very small ; the submedian teeth are tipped with a small 

 mobile spine, and between them is a series of numerous, minute, 

 closely placed and pectinately disposed spinules ; between the 

 lateral marginal teeth are also one or two spinules. The 

 penultimate joint of the raptorial limbs is slender and armed 

 with a small spine at its infero-distal angle ; the dactylus is 

 slender, arcuate, and without any spines on its inner margin. 

 The appendages of the thoracic limbs are slender, not dilated. 

 The uropoda are relatively large, and the spines of their 

 basal prolongation are simple. Length rather more than 

 1 inch. 



A small male was in a bottle with Pseudosquilla oculata ; but 

 the locality has unfortunately not been preserved. This very 

 distinct species may be recognized at once by the form of the 

 terminal postabdominal segment and the absence of spinules 

 on the inner margins of the dactyli of the raptorial limbs — 

 both characters which are mentioned by Prof. Alph. M.- 

 Edwards in his brief description.

Under this name I separate two specimens in the Museum 

 collection, one of which was formerly referred to P. ciliata. 

 They are evidently closely allied to P. oculata, which they 

 appear to represent in the Indo-Pacific Region ; but they may 

 be distinguished by the following characters : — The rostrum is 

 not armed with a small median spinule; the longitudinal 

 cannulas of the terminal postabdominal segment are more 

 flattened at base ; and there are only three on each side of the 

 median keel, the small cannula next that of the lateral 

 margins being entirely absent. Length of the largest indi- 

 vidual (a female) nearly 2 inches. 



Hob. Philippine Islands {coll. Brit. Mus., Cuming). 



Besides the female from the Philippine Islands there is a 

 small male individual, from the collection of II.M.S. ' Herald," 1 

 in the Museum collection. As in P. oculata, there is on either 

 side of the carapace a very distinct circular spot, bordered 

 with a pale margin. This latter character, the truncated 

 sides of the exposed thoracic segments, and the more trans- 

 verse rostrum serve to distinguish both P. oculata and P. 

 ornata from P. ciliata.
