Coutiere has recen-tly (1907, 1 and 2) referred numerous 

 larvae known by the name of Anisocaris to the family Pasi- 

 phaeidae, and considers that Caricyphus angulatus, Spence 

 Bate (1888) is a closely allied larval form. While in no way 

 dissenting from this view, it may be pointed out that C. angu- 

 latus and the forms of Anisocaris, with their long rostrum and 

 pronounced elbow on the third abdominal somite, are strik- 

 ingly different from any stage in the development of P. sul- 

 catifTons. 



General distrihution . — In the W. Atlantic this species is 

 known from between lat. 35° 12' and 41° 53' N., and long. 

 65° 35' and 74° 57' W. (Smith) ; in the N.E. Atlantic it has 

 been recorded from three stations to the south and west of 

 Iceland (Hansen). In the British Museum there is a single 

 specimen, an ovigerous female 70 mm. in length, which was 

 presented bv Canon Norman^; it was taken in 1875 by the 

 Valorous expedition in lat. 52° 33' N., long. 26° 44' W. I 

 have also examined a specimen found by the Thor as fol- 

 lows : — 



10/7/'04— 61° 34' N., 19° 5' W. Soundings, 1180 fathoms. Mid- 

 water trawl, 0-985 fathoms — One, 16'5 mm. 



Irish distrihution. — P. sulcatifrons has been found rather 

 frequently in deep water off the west coast. Large specimens 

 are not common ; the adults possibly occur in greater abun- 

 ance further off shore. The records are : — 



Helga.

1 In the bottle with the specimen is a note, in Norman's handwriting, 

 which states that the specimen was erroneously recorded by him in the 

 Proceedings of the Ro3'al Society as Pasiphae tarda.
