in the shape of small expansions at the base of the stem of the 

 gill." While this is not the case with the Indian species — Alcock 

 found that they fell readily into two groups — the passage quoted 

 above, coming as it does from a high authority on crustacean 

 morphology, seems to show that the two groups merge in the 

 Eastern Pacific and we propose, therefore, to combine once more 

 the genera Polycheles and Pentacheles.

Zool. Invest., Crust., pi. x, fig. 2. 



One female, 70 mm. in length, was obtained at St. 391. 



This specimen agrees in all its characters with examples 

 described by Alcock under the name of P. hextii ; but we are of 

 the opinion that the form which has received this name is 

 identical with the older Polycheles typhlops of Heller, a species 

 hitherto known only from the Mediterranean and East Atlantic. 



We have closely compared specimens of P. hextii with two 

 examples of P. typhlops obtained b}^ the ^ Talisman ' expedition 

 off the Cape Verde Islands and with a large drawing of a specimen 

 from the W. coast of Ireland. The only difference that we have 

 been able to discover is that the epipod at the base of the outer 

 maxillipeds is a trifle larger in the Atlantic specimens ; but the 

 spinulation and proportions of examples from the two localities 

 and the peculiar character of the orbit correspond so precisely 

 that the specific identity of the two forms cannot be doubted. 



The species affords yet another illustration of the wide-spread 

 distribution of man}^ deep-sea Crustacea.
