STJTEE: new NOK-MAKIKE MOLLUSCA from new ZEALAND. 289 



No figures of F. fulminata having ever been published, I take this 

 opportunity of giving some (Figs. 8-85) after a specimen in my 

 collection from Stewart Island. 



Animal with a distinct caudal pore. 



Jaiv the same as in the other species of Phacussa. 



Radida has the formula 25 : 15 : 1 : 15 : 25, having four more 

 teeth in each transverse row than the type, as described and figured 

 by Capt. Hutton, but otherwise the teeth are very much of the same 

 character. The central tooth is tricuspid, with the side cusps minute, 

 the laterals lack the entocone, the mesocone being large, these are 

 followed by four transitional teeth, and there are 21 marginals with 

 an oblique mesocone only. 



The Reproductive organs (Fig. 9) are very simple. The penis is 

 broadest at its distal end, at the outer end the retractor muscle is 

 inserted, and opposite to it the vas deferens enters. The free oviduct 

 is long and cylindrical, and on the side towards the male organ the 

 oblong receptaculum seminis, with a short distal caecum, takes its 

 origin a little above the vestibule. 



In Phacussa liypopolia, Pfr., the genital organs are very similar. 



5. Flammtjlina (Phacussa) Henkyi, n.sp. PI. XV, Figs. 10-13. 



Shell (Figs. 10-105) subcliscoidal, umbilicated, with a low depressed 

 conical spire, uniformly light brown, not shining, rather thin, 

 costulate ; whorls 5, first slowly and then more rapidly increasing; 

 protoconch of IJ whorls faintly microscopically decussate, the other 

 whorls with sharp, subequidistant riblets, about 3 per mm., the 

 interstices microscopically decxissated by numerous incremental and 

 spiral striae ; the 1 ^ whorls following the protoconch are sometimes 

 ornamented with rufous zigzag lines ; suture impressed ; periphery 

 rounded ; aperture oblique, broadly rotundly lunar, peristome simple, 

 with a slight callus inside, that is more pronounced on the columellar 

 lip, which is reflexed towards the umbilicus ; the latter is narrow, 

 open, deep, showing two volutions, umbilical region whitish ; base 

 convex. Diam. maj. 10, min. 8*8 mm. ; alt. 5'5 mm.; diam. of 

 umbilicus 1*5 mm. 



Hah. — Resolution Island. 



Type in my collection. 



I have much pleasure in naming this species after Mr. R. Henry, of 

 Resolution Island, who so very kindly collected a number of shells on 

 this hitherto conchologically unexplored island. 



Animal with parapodial groove and small caudal pore. 



Jaiv (Fig. 11) consisting of numerous vertical, finely longitudinally 

 striated plaits. The figure shows the jaw in the form it had when 

 separatee! from the buccal mass. 



Eadula (Fig. 12) has the formula 24 : 6 : 1 : 6 : 24. The 

 central tooth has a short, heart-shaped reflected portion, with a wide 

 mesocone, not extending to the margin of the basal plate, no side 

 cusps. The admedians have a strong, stout mesocone, at first vertical, 

 but becoming ultimately very oblique and directed inwards, and
