MARINE SILVER HATCHETFISHES — SCHULTZ 641 



rays, 8 to 10 anal photophores, and a very short posttemporal spine, 

 its length equal to width of only 1 or 2 anal photophores. 



Description: Counts made are given in table 1, p. 591, and table 

 6, p. 636. 



Color: The color pattern is shown in figure 16, p. 629. 



Range: This species is known from the Western Atlantic Ocean, 

 off the eastern coast of Florida, Gulf of Mexico, Caribbean Sea, off 

 Nicaragua, off Costa Rica, off Puerto Rico, off British Guiana and 

 Trinidad at depths of 200 to 600 fathoms. Specimens observed are 

 from 19 to 71 mm. in standard length. 



Remarks: Matsubara (Suisan Kenkiu-Shi, Japan, vol. 36, No. 

 l,p.2, 1941; Japanese Journ. Ichthy., vol. l,No.3, p. 192, fig. 3, 1950) 

 reported P. asteroides from Japan, but when I examined his specimens, 

 collected at a later date, I found them to differ from P. asteroides of 

 the Western Atlantic; therefore, the Japanese specimens represent a 

 distinct species, described immediately below.

Holotype: USNM 179793 collected by K. Suzuki at Kumanonada* 

 Japan, standard length 64 mm. 



Paratypes: Collected with holotype and bearing same data, 3 

 specimens, standard lengths 45 to 59 mm., deposited at Kyoto Uni- 

 versity, Maizuru, Japan. USNM 179794 collected with the holotype, 

 standard length 51.5 mm. 



Description: Measurements made on the holotype and four 

 paratypes arc given in table 7, p. 638; the counts made are given in 

 table 1, p. 591, and table 6, p. 636. 



Color: The color pattern is shown in figure 17, p. 630. 



Range: This species has been found only in Japanese waters. 



Remarks: This species is most closely related to P. asteroides in 

 having about the same number of anal photophores, anal rays, and 

 gill rakers, but differs in having only 12 or 13 total dorsal rays instead 

 of the 14 to 17 that occur in P. asteroides. In addition the color pat- 

 tern of P. matsubarai differs from that of P. asteroides in the wedge 

 shaped dark bar a little behind the head being narrow and reaching 

 ventrally to the midlengthwise axis of body, whereas in P. asteroid** 

 this wedge shaped bar is broad and reaches only halfway to the mid- 

 lengthwise axis of bod}^. Behind this dark bar a light or white inter-
