52 The Irish NatiiralUt. March, 



Irish specimens of this species, at any rate, are more brightly coloured. 

 The descriptions of the species are very full, and the comparisons with 

 closely related species not found in the British area are especially valuable. 



The weakest part of the work is undoubtedly that dealing witli 

 <iistribution, especially the extra-British portion. A number of localities 

 are capriciously selected for mention, and the rest ignored. For instance, 

 one might infer Irom the description of Aricia Latreillil on p. 502, that 

 it had been found only at St. Andrew's and the Firth of Forth, .\pparently 

 this subject is not so important in Professor Mcintosh's eyes as in those 

 of most Irish biologists. Recently ' Professor Mcintosh published a list 

 of the Irish localities of the species described in this volume. In thiij 

 list is the name of a new species, Aricia Buskii. but there is ito mention 

 of it in the Monograph. It is very desirable that this nomen nudum should 

 be quickly supplemented by an account of the structure and specific 

 characters of this species. Professor Mcintosh is guilty of the heinous 

 nomenclatural crime of describing as new in this volume, species which 

 he described some years ago in the A nnals and Alagazine of Natural 

 History. 



Under Autolytus inermis (p. 247) there is no mention of the fact that 

 this species was separated as the type of a new genus Autolylides by 

 Malaquin.2 It is distinguished from all other species of the genus 

 Autolytus by having a proboscis devoid of teeth. 



Of special interest to Irish zoologists is the species which Mcintosh 

 records as Eunice floridana, Pourtales. This worm is always found 

 associated with the branching coral Lophohdia pmlifcra, or a species of 

 Amphihelia. and is abundant in deep water off the west coast of Ireland. 

 The worms live in a parchment-like tube which usually perforates a 

 branch of the coral. It seems more probable that the coral grows up 

 round tlie tube than that the worm bores into the coral, as the free ends 

 of the worm-tube generally project beyond the coral. This species was 

 described as new, under the name Eunice philocorallia, by Miss F. 

 Buchanan,-' who pointed out its close resemblance to E. floridana. Shortly 

 afterwards * she published a note stating that the species appeared to 

 be identical with one previously described by Storm as E. Gunneri. 

 Professor Mcintosh omits any reference to this revised opinion and does 

 not mention E. Gunneri. 



In this volume, three species are described which occur on the west 

 of Ireland, but nowhere else in the British marine area. These are 

 Lumbriconereis hibertiica, Mcintosh ; Eunice floridana, Pourtales ; and 

 Onuphis fra^osa, Ehlers.
