Ireland. The shallower waters of the west of Ireland have 

 long been known to be extremely rich with respect to their 

 Invertebrate fauna. But now Mr. E. W. L. Holt and his 

 able coadjutors have carried investigations down to 500 and 

 even 1,000 fathoms, and have brought to light a fauna of 

 extraordinary richness. The material has as yet only been 

 partially worked out, but the results in many classes are 

 truly astonishing, including species previously only known in 

 distant localities north and south, together with a large 

 proportion of new forms.
