been found several times ott the Cork and Kerry coasts in 

 Bantry Bay, Kenmare Kiver, near the Skelligs, and at 

 Valencia. An occasional specimen was found in Ballynakill 

 Harbour, Co. Galway, during the period in which the marine 

 laboratory was stationed there and examples have also been 

 obtained in Blacksod and Clew Bays, Co. Mayo. In the north 

 P. Montagui has been found in some abundance off the Antrim 

 coast. 



Vertical range. — Earely found in the Irish Sea in more than 

 35 fathoms of water ; in the area known as " Rathlin Deep," 

 off Co. Antrim, it has occurred between 100 and 130 fathoms, 

 this being about the maximum depth in which P. Montagui 

 is found in European waters. In the Pacific the species 

 ranges from 3 to 351 fathoms (Rathbun), w^hile several speci- 

 mens are recorded from 430 fathoms off the east coast of N. 

 America (Smith).

Colour in life. — The carapace is sometimes uniform pale red, 

 but the posterior quarter is often colourless. The rostrum is 

 bright red distally, proximally paler and dotted with red. 

 There are transverse bands of red on the first abdominal somite, 

 on the anterior parts of the second and third and on the pos- 

 terior parts of the second, third and fourth ; these bands are 

 darkest and wddest dorsally. The fifth somite is pale red, with 

 darker dots ; while the sixth somite , telson and uropods are of 

 a rather deeper tone of red. The eyes are black or dark grey, 

 with golden reflections. The antennular peduncle and an- 

 tennal scale are pale red with darker dots ; the flagella are all 

 bright red. In specimens from deep water the third maxilli- 

 pede and five pereiopods are all pale red, with the exception of 

 the chelae of the second pair, which are colourless. In speci- 

 mens caught in shallow water the carpus and the greater part 

 of the propodus of the last three pairs are pure milk white in 

 colour, thus contrasting very strongly wdth the bright red 

 dactylus and distal extremity of the propodus. This colour- 

 ing, when present, affords a ready means of separating P. pro- 

 pinquus from any of the allied species which may occur in the 

 same haul, while it may be noticed in addition that there are 

 no oblique bands of red on the carapace as irf P. Montagui, nor 

 yellow pigmentation on the body as in P. Bonnieri. 



Size. — The largest specimen examined measures 86 mm. ; 

 an ovigerous female is only about 50 mm. in length. Wolle- 

 baek has recorded an example of 150 mm.
