spines on the carapace is a character not found in any of our 

 specimens, while the small size (about 19 millim.) and littoral 

 habitat (" in a small sand-pool in the Zostera-ha.nk at 

 Sandycove, Kingston ") help to strengthen the probability 

 that Kinahan had before him only a young and possibly some- 

 what aberrant specimen of P. Montagui*. 



The species described by Caullery (7. c.) as Pandalus 

 {Dichelopandalus) Bonnieri appears to differ in no essential 

 point from the present form. By the great kindness of 

 M. Caullery I have been permitted to examine two of the 

 type specimens. Both unfortunately were very imperfect 

 (as were all the specimens obtained), but, so far as could be 

 seen, presented no differences from our specimens save in their 

 smaller size. As Caullery's figures show, they agree in the 

 characteristic points of the exopod on the third maxillipeds, 

 the long and slender dactyli of the ambulatory legs, and the 

 presence of only three spinules on the carapace behind the 

 rostrum. From the description we also gather that the carpus 

 of the second leg is five-jointed. Since I believe that 

 Kinahan's name cannot properly be applied to the present 

 species, that used by Caullery will take its place ; and as his 

 subgenus Dichelopandalus may be left in abeyance till it is 

 shown not to be synonymous with the genus itself, the name 

 for the species defined above will be Pandalus Bonnieri^ 

 Caullery. 



Size. — The total length of our largest specimen is about 

 110 millim. 



Occurrence. — About a dozen specimens are in our collection 

 from various localities in Loch Fyne and Loch Long from 

 depths of 40-105 fathoms. The only other locality within 

 the British area from which it has yet been recorded is off the 

 south-west coast of Ireland, 214 fathoms (Caiman, Trans. 

 Roy. Irish Acad. xxxi. pt. .1, 1896, p. 6). I have also 

 examined specimens taken in 120 fathoms off Rockall {torn, 

 cit. p. 77). Prof. Sars records it from Norway at depths 

 of 60-150 fathoms, and the ' Caudan ' dredged it in the 

 Bay of Biscay at from 180 to 1200 metres. It is probable 

 that this species as well as P, propinquus has been frequently 

 confounded with the common P. Montagui. Prof. Henderson, 

 in his " Decapod and Schizopod Crustacea of the Firth of 

 Clyde" (Trans. Nat. Hist. Soc. Glasgow, 1886, p. 36, sep. 

 copy), says of P. annulicornis ( = Montagui) , " Many examples 



* The name leptorhynehus was afterwards independently used by 

 Stiinpson for an Australian species of Pandalus very different from any 

 of the forms here discussed (Proc. Acad. Nat. Sci. Philadelphia, 1860, 

 p 38).
