34,6 DE. H. J. HAKSEN OK THE 



sj)ecimens from Naples were taken in a depth of about 25 fathoms 

 together with C. lorealis. In material received from Mr. Dollf us 

 was found a large number of specimens from Le Croisic (south- 

 western coast of Brittany), captured by E. Chevreux, and some 

 specimens from Villefranche. The specimens from the Adriatic 

 wrongly referred to C. hirtipes, H. M.-Edw., by Heller, Stalio, 

 and Stossich, belong in all probability to G. neglecta. DoUfus 

 enumerates (I. c.) nine stations in the western part of the 

 Atlantic ; one of these is near Belle-Isle (not very far from 

 the south-westera coast of Brittany), 19 m., while the re- 

 maining eight stations are between lat. 39° 18' N. and lat. 30° 

 1|' N., with depths from 1007 down to 1924 m. ; finally, he has 

 seen specimens from the Bay of Griardini, Sicily, 16 m., and from 

 the Adriatic. Dollfus states that the pigmentation of the eyes 

 is still distinct in specimens captured at depths down to 1200 m., 

 but disappears completely in the animals from greater depths, 

 though the eyes always exist. It may be taken as certain that 

 his specimens from deep water belong to this species, while I am 

 inclined to suppose that all those from 1007 to 1924 m. belong 

 to a species closely allied to G. neglecta ; but not having seen 

 any of these specimens, I cannot settle the question. I may 

 add that it is probably almost without parallel that a species 

 which has been taken in several places far from each other 

 in depths ranging from about 8 to 25 fathoms, should not occur 

 in depths from about 25 . (or at most 50 fathoms) and down 

 to more than 500 fathoms, but yet should haye been found not 

 less than eight times in depths from about 550 to 1000 fathoms. 

 Besides, I can state from personal experience that species 

 of the genus Girolana are frequently so closely allied that a 

 minute examination of the shape of the posterior thoracic 

 epimera, the shape and armature of last abdominal segment, the 

 length and breadth of the rami of the uropoda, the distribution 

 of plumose setse on seventh thoracic legs, &c., is necessary in 

 order to avoid erroneous determination. 



RemarJcs. — This species is distinguished from the two pre- 

 ceding forms by shape and colour of the eyes, the posterior 

 thoracic epimera, the second joint of seventh thoracic legs, the 

 shape and armature of last abdominal segment, and the com- 

 paratively greater breadth of the rami of the uropoda. In the 

 paragraph on occurrence and distribution some further remarks 

 on the species — or two species — are found.
