462 REVISION OF HETEROMI—GOODE AND BEAN. vol.xvii. 



from the same region at 932 meters; two from tlie Banc D'Arguiu at 

 1,495 meters. These last have been made the subject of an elaborate 

 description by Vaillant, who also publishes a good figure. 



This species is distinguished from K. sexspiyiis, (fig. 192A-B), 

 described by Eichardson from Australian Seas* and subse(j[uently 

 described by Giinther, who also gives an excellent figure t by the various 

 characters, most striking of which is the difference in the relationships 

 of the position of the dorsal spines aiul tbe soft anal fin. In N. sexspinis 

 the dorsal and soft anal do not pass the same vertical, whereas in N'. 

 mediterraneus the last three dorsal spines are placed over the anterior 

 part of the soft anal. The National Museum is indebted to Dr. Giin- 

 ther for a specimen of Notacanthus sexspinus from 'New Zealand (No. 

 12625, U.S.N.M.). It is a small specimen, and does not exhibit any 

 inflation of the cheeks, such as is shown in the plate in the Challenger 

 report. It has eight dorsal spines. 



The type of N. mediterraneus from Nice was examined by Giglioli at 

 the Turin Museum in 1882, Its total length is 203 mm., and its radial 

 formula D. 6 / 1; A. 12 / 132?; V. 3-4 / 8; C. 51 



Prof. Giglioli informs us that in his " Central Collection of Italian 

 Vertebrates " at Florence he has four sj)ecimens of JSf. bonapartii, as 

 follows: 



a. Nice, August 11, 1882. Total length, 153 aim. D. 8 / 1 ; A. 6-7 / 120; V. 3 / 6-7; 



P. 9-10; C. 3-4 ?. A large curved spine iu upper corner of mouth on either 



side. 

 i. Nice, March 7, 1891. Total length, 205 mm. D, 7 / 1; A. 14 / 120; V. 3 / 7. 



P, 12. C. 4?. Buccal spines hidden in skin. 



c. Nice, June 15, 1892. Total length, 203 mm. D. 7 /I. A. 8 ? / 140. V. 3 / 5-7, 



P. 10 / 12. Buccal spines large and prominent. 



d. Syracuse, 1855-'60?. D. 7 / 1. A. 11 / 25. P. 9-10. V. 3 / 5, Tail broken off. 



Buccal spines conspiciious. 



Another sj)ecimen, collected by Bellotti at Messina, December 12, 

 1882, and now in the Museo Civico at ^Nlilan, Avas examined by Giglioli, 

 who states that it was 104 mm. long, and had D. 7 / 1. A. 7 / 1 V. 

 3 / 6. P. 10-12. C. 5 1
