 In 1909 I received, through Mr. R. Southern, of Dublin, a small collection 

 of Irish Maldanidae, belonging to the Irish National Museum, for description. 

 The collection contained only a few determinable species — those which are 

 hereafter discussed. Amongst these are two which, though not quite 

 unknown before, have not been previously described. In addition, the 

 collection contains Praxillura sp., from the south coast of Ireland (Station 

 R. 30 ; 8, p. 127) ; Petaloproctus sp., from the west coast (W. 115 ; 10, 

 p. 170) ; a species which is possibly near akin to Isocirrus, from the same 

 locality as Praxillura; Leiochone sp. [dfpeata ?], from the west coast (W. 115 

 10, p. 170, and L. 29t)-L. 300 ; 6, p. 41) and the east coast ^S. 166 ; 6, p. 69) 

 Leiochone sp. \cirrata-lorealis-gxo\v^\ from the south-west coast (S. E. 172 

 6, p. 84, and S. E. 590 ; 9, p. 156) ; Praxillella sp. [c/racilis-grow^ ; cf. 5, p. 190], 

 fi'om the the south-west coast (S. R. 16 ; 10, p. 165) ; Euclymene sp. [a 

 large species], from the south coast (E. 30 and E, 31 ; 8, p. 127) ; and in 

 addition to these, at least four species, all belonging to the Tribus 

 Euclymenini (E. 31; 8, p. 127; S.E. 5; 6, p. 64; S. 273; 7, p. 102; 

 Kingstown-Dalkey, 14'6-22m. [20/7, 1907]). 



Nicomache (Nicomache) maculata n. sp. 

 (Plate XVIIL, figs. 13-19 ; Plate XIX., figs. 27-30.) 



" Nicomache lumbricalis (Fabricius)," Cunningham and Eamage (1, p. 678, 

 fig. 41), and Michaelsen (4, p. 39); cf. 5, pp. 99 and 95. 



Specific Diagnosis. — The anterior part more or less distinctly speckled ; 

 especially conspicuous is one rounded spot outside each nuchal organ, and 

 one or more transverse bands of colour on the back of the fore-part. Ocelli are 

 present. Twenty-two setigerous segments and one (as a rule quite) achaetous 

 posterior segment. The cup-shaped section at the hindmost extremity is short, 

 and but little longer on the ventral side than on the back. The anal cirri are 

 not characterized by different sizes. Nephridia in setigerous segments 6-9. 

 The front part of the body is not particularly strong in glands — at any rate not 

 the hinder part of the segments iu this region ; on the hinder segments
