A. Eibs of shell narrower than the grooves ; five above the periphery. 



Foot black ; tentacles black. 



B. Eibs of shell narrower than the grooves; seven above the periphery. 



Foot black ; tentacles margined with white. 



C. Eibs of shell broader than the grooves ; five or six above the 



periphery. Foot variegated. 



Pakmophokus unguis. Mantle ample, covering the whole foot and head, 

 expanded on each side, with a simple margin, fissured in front. Tentacles 

 two; eyes at their outer bases. A row of short cirri on each side of the 

 neck and foot. Gills two, symmetrical, outside the shell, under the mantle ; 

 a round white renal organ at their apices. The whole body dark blue- 

 black ; mantle paler below ; sole of the foot white. Habits nocturnal. 



Patella inconspicua. Animal yellowish white ; head dark purple ; 

 tentacles with the outer half purple, very broad at the base and tapering. 



Doris longula ? Body oval, depressed ; mantle large, expanded all 

 round, with a smooth margin, finely granular ; rhinophores conical, short, 

 thick, and ringed ; branchiae six, each double ; length 1-5 inch ; breadth 

 •8 inch. Foot bright orange, showing the dark-coloured liver through it ; 

 mantle orange-yellow, freckled with small round white spots which form a 

 more or less reticulated pattern ; branchiae yellow-orange ; rhinophores 

 orange. 



This description applies to two specimens that I found in Lyttleton 

 harbour, and which I think must be D. longula. The specimens are now 

 in the Canterbury Museum. 



Phidiana longicauda. Although Quoy describes the tentacles as clavate, 

 he figures them as tapering. The generic position therefore of the animal 

 must remain uncertain until it is re-discovered. 

 Montagua coefei, sp. nov. 



Last September Mr. C. C. Corfe of Christ's College brought me two 

 living specimens of a beautiful little Nudibranch which he had collected at 

 Governor's Bay in Port Cooper. As the species has not yet been described 

 I have much pleasure in dedicating it to its discoverer. It belongs to the 

 genus Montagua of Gray. 



Tentacles approximated, tapering, standing erect at some distance behind 

 the oral tentacles ; a minute eye at their outer bases. Oral tentacles distant, 

 tapering, half as long again as the tentacles. Body prolonged posteriorly 

 into a long tapering tail. Branchi^ in four or five rows on each side of the 

 back ; crowded, linear, pointed, unequal. Foot grooved along the centre, 

 the margin thin ; contracted anteriorly and then produced on each side into 

 a curved tapering fold directed backward. 



Foot, back, tentacles, and oral tentacles translucent white ; a dead white
