PsEUDOcucuMis BicoLUMNATUS, Dendy. 



Journ. Linn. Soc, vol. xxvi., No. 166, "Holothurians of New 

 Zealand." 



There is an excellently preserved and very typical speci- 

 men of this species collected by Dr. J. C. Verco. 



Phyllophorus ventripes, n. sp. Plate ii., fig. 1. 



The collection contains several specimens of a VhyUo- 

 phorus which apparently belongs to a species not hitherto 

 described. They were collected by Dr. J. C. Verco. 



Description. — Length, about 60 mm. ; shape, fusiform, 

 and truncated anteriorly. The podia are restricted to the 

 mid-ventral region, and are numerous and thickly disposed 

 in both the radial and inter-radial areas ; a very small number 

 of imperfectly developed podia may occur scattered outside 

 of the region referred to, but the mid-dorsal region for a 

 space of about 30 mm. by 10 mm. is devoid of any podia or 

 papillae. The calcareous ring consists of ten compound mem- 

 bers, both the raidial and inter-radial having posterior pro- 

 longations (plate iii., fig. 5). 



There are no calcareous deposits in the perisomei. The 

 podia are provided at their terminations with cribriform 

 plates and supporting rods. The tentacles, twenty in num- 

 ber and disposed in the typically generic manner, contain 

 stout branched rods having expanded perforated ends which 

 -are often bifurcated. 



The most remarkable feature of this species is the distri- 

 bution of the podia. We know of but one other species in 

 which that feature is the same, viz., Thyone fueridionaliSy 

 Bell, and but for tlie circumstance that the arrangement of 

 the tentacles in our species is quite typical of the genus 

 Fhyllophorus, we should not have hesitated to identify it 

 with that of Bell, since it agrees well with the latter in all 

 other respects. 



Thyone vercoi, n. sp. 



There is a single specimen collected by Dr. J. C. Verco. 

 The animal is of a brown colour, and apparently considerably 

 ■contracted. Its length is 36 mm., and it tapers both pos- 

 teriorly and anteriorly, the latter extremity being truncated. 

 The podia appear to be thickly disposed over the whole of 

 the body, but are, perhaps, not quite so numerous on fhe 

 dorsal surface; no arrangement in rows is discernible any- 

 where. The calcareous ring is of substantial build, and con- 

 sists of ten composite members, the radial pieces being 

 prolonged posteriorly. The tentacles are ten in number, the 

 dorsal being about two and one-half times as long as the 

 ventral.
