process from the base of the uropod the outer margin of the 

 longer spine anterior to the weh-developed lobe is never concave ; 

 it is occasionally feebh^ sinuous, but in nearly every instance is 

 definitely convex. 



Very numerous specimens, the largest 119 mm. in length, 

 exhibit the above characters with most remarkable constancy. 

 They were taken at localities ranging from Hongkong to the Per- 

 sian Gulf. 



Squilla wood-masoni, sp. nov. 



SqiiUla polita, Wood-Mason, MS., nee Bigelow. 



Squilla wood-masoni may be separated from 5. oyatoria, its 

 variety perpcnsa and 5. interrupta by the use of the following 

 characters : — 



The dorsal surface of the carapace and abdomen is smooth, 

 highly polished and without trace of punctuation. The carapace 

 is shorter and broader than in any of the preceding forms, its 

 breadth at the antero lateral angles being at least one half its 

 length including the rostrum. The anterior bifurcated portion o[ 

 the median carina of the carapace is entirely obsolete. The distal 

 edge of the ophthalmic somite is produced to a small point between 

 the bases of the eyestalks and is not truncate or slightly emarginate 

 as in the preceding forms. The eyes are large, much as in 

 5. oratoria, and the carpus of the raptorial claw also resembles that 

 species in bearing three or four tubercles on its dorsal edge. The 

 dact^dus of the same limb is strongly sinuate externally and is of a 

 much more clumsy build than in any of the preceding forms. The 

 bifurcate process of the uropod is similar to that of 5. oratoria, 

 but the lobe on the external margin of the longer spine is, in all 

 except very young specimens, much smaller. 



Numerous examples, the largest 109 mm. in length, from 

 localities ranging from Hongkong to Aden. 



Squilla annandalei, sp. nov. 



This species is closely allied to the well-known 5. raphidea, 

 Fabr., and the propodus of the raptorial claw bears, as in that 

 species, a number of large fixed spines along the margin opposed to 

 the dactylus. It may be distinguished by the following features : — 



The rostrum is shorter — more so than in the form of 5. raphidea 

 which de Haan described under the name of harpax— and its 

 apex is more broadly rounded. The antennular peduncle is longer 

 than the rostrum and carapace combined. The anterior lobes of 

 the lateral margins of the sixth and seventh thoracic somites are 

 quite distinct, whereas they are wholly obsolete in S. raphidea. 

 The sublateral carinae of the last three thoracic and the submedian 

 carinae of the last two abdominal somites end in spines. The mar- 

 ginal spines of the telson are sharper than in S. raphidea and the 

 inner uropod is narrower in proportion to its length.
