130 FISH AND FISH-LIKE ANIMALS OF N.S.W. 



370g. S. pleurogramma. Tetrodon pleurogramma Regan, P. Zool. Soc. 

 1902, ii., 1903, p. 300, pi. 24, 2. 



Not uncommon. Length 7 inches. 



MeCulloch and Waite, Tr. Roy. Soc. S. Aust. xl., 1916, p. 450, have united 

 this species with S. altipinnis Ogilby, but this is apparently incorrect. 



The specimen recorded as Tetrodon erythrotaenia from Sydney by Kner, 

 Novara Zool. i., 1867, p. 408, was perhaps referable to S. pleurogramma. 



S. richei Freminville, has been recorded from Sydney by Kner, Novara Zool. 

 1, 1867, p. 407. Though common in Southern Australia, there is no evidence 

 that it occurs in New South Wales waters. 



CLXI. Family Diodontidae. 



A. All the spines with two roots and movable. Diodon (371). 



AA. Most of the spines fixed, with 3 roots. 



B. Anterior spines 2-rooted and movable; about 12 dorsal and anal rays. 



Dicotylichthys (372). 

 BB. Anterior spines 3 rooted; 15-16 dorsal and anal rays. Allomyclerus (373). 



371. Diodon Linne, Syst. Nat. 10th. ed., 1758, p. 334 (hystrix). 



371a. D. holocanthus. Id. Linne, Ibid., p. 335. Paradiodon quad ri ma- 

 cula t us Bleeker, Atlas Ichth. v., 1805, p. 58, pi. 212, 2. 



A tropical species of which the young sometimes wander southward into 

 New South Wales. Length 12 inches. 



D. hystrix Linne, was included in a mere list of Port Jackson fishes by 

 Castlenau, P.L.S. N.S.W. iii., 1879, p. 357. As it has not been since recognised 

 from these waters, further proof of its occurrence is necessary. 



372. Dicotylichthys Kaup, Arch. Naturg. xxi., 1855, p. 230 (punctulatus) . 

 372a. D. punctulatus. Porcupine-fish. Id. Kaup, Ibid.; Id. Waite, 



Mem. Austr. Mus. iv. i., 1899, p. 98, pi. 19 (Fl. xliii.). 

 Very common in estuaries and inlets along the coast. Length 12 inches. 



373. Allomycterus MeCulloch, Rec. Austr. Mus. xiii. 4, 1921, p. 141 



(jaculiferus). 

 373a. A. jaculiferus. Porcupine-fish. Diodon jaculiferus Cuvier, Mem. 



Mus. Hist. Nat. iv., 1818, p. 130, pi. 7. A. jaculiferus MeCulloch, Rec. 



Austr. Mus. xiii. 4, 1921, p. 141, pi. 33, 2. 

 Commonly taken by trawlers in moderately deep water. Length 12 inches. 



CLX1I. Family Molidae. 



374. Mola Koelreuter, Novi Comm. Act. Petropol. viii., 1770, p. 337 

 (aculeata) . 

 374a. M. mola. Sun-fish. Tetrodon mola Linne, Syst. Nat. 10th. ed., 

 1758, p. 334. Orthagoriscus mola Schlegel, Faun. Japonica, Pisces,

 Apparently not rare off the coast, and occasionally stranded on ocean beaches. 

 Length 10 feet.
