ments in large males (filaments becoming ex- 

 tremely long in largest males), increasing in 

 length with increase in SL. Length of upper lobe 

 of caudal fin ca. 29.4 to >128 (ca. 44), varying 

 from ca. 30.1 to >35 in females more than ca. 

 80 mm. SL and from ca. 34.3 to >128 in males 

 more than ca. 85 mm. SL. Length of lower lobe 

 of caudal fin ca. 28.0 to >111 (ca. 39), varying 

 from ca. 29.5 to >34 in females more than ca. 

 80 mm. SL and from ca. 32.4 to >111 in males 

 more than ca. 85 mm. SL. 



Values for depth of body, lengths of fins and 

 fin-lobes, length of base of anal fin, and lengths 

 of anal spines are based on measurements of 

 more than 110 specimens; those for all other 

 morphometric characters listed above on meas- 

 urements of a graded size series. 



Coloration 



Live coloration is unknown, but a 35-mm. 

 color photograph was taken shortly after 

 capture of a male specimen (TABL 101317, 120 

 mm. SL) from Silver Bay station 5191. Iris 

 silvery, except for a little orange on dorsal cur- 

 vature, some dull yellow to dark gray on anterior 

 curvature, a little light gray on ventral curva- 

 ture, and considerable dark gray on posterior 

 curvature. Head mostly bright orange. Body 

 mainly bright orange, except ventrolateral sur- 

 face of anterior end of body silver with some 

 orange. Area beneath base of dorsal fin red- 

 orange. Dorsal spines and soft rays mostly 

 orange. First interradial membrane of dorsal 

 fin red-orange; a somewhat triangular silvery 

 area on proximal portions of second through 

 sixth interradial membranes; an elliptical 

 orange to red-orange area on proximal portions 

 of seventh through ninth interradial mem- 

 branes; distal part of membrane of soft dorsal 

 fin dull orange; remainder of dorsal fin mostly 

 dull yellow. Area above base of anal fin bright 

 orange. Anal fin not clearly visible. Pectoral fin 

 orange basally, rest of fin pale to silvery. Pelvic 

 spine and filamentous first pelvic soft ray 

 silvery, rest of pelvic fin orange proximal ly 

 grading into light orange or pink and then into 

 dull yellow distally. Outer rays (including fila- 

 mentous ones) of both lobes of caudal fin red- 

 orange; inner two or three rays of each lobe 

 and midcaudal rays dull yellow to silvery distally 



(i.e., dull yellow to silvery inner area of caudal 

 fin crescent shaped), orange proximally. 



A less distinct, 35-mm. color photograph of 

 a smaller specimen presumably from Silver Bay 

 station 5191 shows no pronounced differences 

 from the above description except that the fins 

 (particularly the dorsal and pelvic fins) are 

 paler. 



A 35-mm. color photograph of a male speci- 

 men (TABL 101316, 134 mm. SL) from Oregon 

 station 5414 shows some differences from the 

 preceding description. Iris mostly orange. Head 

 and fins much less brightly colored. Dorsolateral 

 surface of body dull orange overlying pale blue. 

 Ventrolateral surface of body mostly silvery 

 with some pale blue on caudal peduncle. 



All photographed specimens were collected 

 during daylight. Those from Silver Bay station 

 5191 were photographed in sunlight, the one 

 from Oregon station 5414 in artificial light 

 (PROX-0-LITE). It is not known whether the 

 differences in coloration mentioned are real or 

 a result of differences in lighting used in the 

 photography. (Frederick H. Berry and George 

 C. Miller made the photographs, which are de- 

 posited in the collection of color slides at 

 TABL.) 



Thirty-one days after capture (and shortly 

 after transfer to isopropyl alcohol) notes were 

 made on the color remaining on the three speci- 

 mens of S. berryi (TABL 101315, 92-99 mm. 

 SL) collected by the Undaunted off British Hon- 

 duras. Dorsal part of head with considerable 

 orange on two specimens (females of 92 and 98 

 mm. SL). Dorsal part of body (particularly 

 above lateral line) with much orange on the 

 female of 98 mm. SL. Membrane of dorsal fin 

 (particularly spiny dorsal) with much dark 

 pigment on all three specimens. Filament of 

 lower caudal lobe red on one specimen (a male 

 of 99 mm. SL). Distal tip of upper caudal lobe 

 with some dark pigment on both female speci- 

 mens. Distal tip of lower caudal lobe with some 

 dark pigment in female of 92 mm. SL. 



In alcohol, specimens gi-eater than ca. 80 to 

 90 mm. SL are usually a light straw color except 

 for small spots of dark pigment usually arranged 

 in irregular rows along the side of the body 

 and in one or two (usually two) rows on the 

 dorsal surface of the caudal peduncle; heavy
