Gonostoma atlanticum (25 occurrences, 48 larvae).—This 
species was not abundant but was found throughout the area on 
both cruises. 
Identification.—Ahlstrom (1974). 
Vinciguerria nimbaria (47 occurrences, 100 larvae).— Vin- 
ciguerria nimbaria occurred throughout the area and did not ex- 
hibit any seasonality. Houde et al. (footnote 4) also found this 
species to be the most common Vinciguerria in the eastern Gulf of 
Mexico. 
Identification.—Ahlstrom and Counts (1958). 
Vinciguerria attenuata (4 occurrences, 6 larvae).—This species 
was rare; Houde et al. (footnote 4) also found this species to be 
the least abundant Vinciguerria in the Gulf of Mexico. 
Identification.—Ahlstrom and Counts (1958). 
Vinciguerria poweriae (2 occurrences, 2 larvae).—This species 
occurred at only two locations during the summer cruise. Houde 
et al. (footnote 4) found this species to be almost as abundant as 
V. nimbaria in the Gulf of Mexico. 
Identification.—Ahlstrom and Counts (1958). 
Bonapartia pedaliota (4 occurrences, 4 larvae).—This species is 
rare; Houde et al. (footnote 4) collected only one specimen in the 
Gulf of Mexico. 
Identification.—Jesperson and Taning (1919) and Grey (1964). 
Maurolicus muelleri (3 occurrences, 3 larvae).—This species is 
rare. Houde et al. (footnote 4) found this to be the most abundant 
gonostomatid in the Gulf of Mexico and the 20th most observed 
species in their collections. This species ranked third in abundance 
in Ahlstrom’s (1971, 1972) eastern tropical Pacific data, although 
Nellen (1973) reported only three specimens from the western In- 
dian Ocean. 
Identification.—Okiyama (1971). 
Type ‘‘Alpha’’ (2 occurrences, 2 larvae).—This unusual larva 
was found at two stations near the Antilles. It is the first record of 
this maurolicine type from the Atlantic, having been found first in 
the Pacific by Ahlstrom (1974). Ahlstrom presumed that this 
might be the larval form of Neophos because of similar vertebral 
counts. Neophos is not known from the Atlantic, thus the iden- 
tification of this larval form remains an interesting question. 
Identification.—Ahlstrom (1974). 
Margrethia obtusirostra (17 occurrences, 21 larvae).—This 
species occurred sporadically throughout the area. Houde et al. 
(footnote 4) reported only one specimen from the Gulf of.Mexico. 
Identification.—Grey (1964) and Ahlstrom (1974). 
Other Gonostomatines.—Four other species of gonostomatine 
larvae occurred rarely and only seasonally. Woodsia nonsuchae 
occurred only in the summer as did Diplophos taenia. Yarella 
blackfordi and Valenciennellus tripunctulatus occurred only in 
the winter. These species were either very rare or not collected by 
Houde et al. (footnote 4) in the Gulf of Mexico. Ahlstrom (1971, 
1972) found significant numbers of Yarella argenteola in the 
eastern tropical Pacific. Both Ahlstrom (1971, 1972) and Nellen 
(1973) reported the presence of Jchthyococcus in their respective 
waters. 
Identification.—Grey (1964) and Ahlstrom (1974). 
Argyropelecus spp. (7 occurrences, 11 larvae).—Larvae of this 
genus were sparse, Occurring only between Florida and Cuba in 
the summer and scattered in the winter. Houde et al. (footnote 4) 
caught 70 specimens in the Gulf of Mexico; Ahlstrom (1972) 
reported that this genus accounted for 15% of sternoptychid lar- 
vae in the eastern tropical Pacific. 
Identification.—I followed Jespersen and Taning (1926) and 
Sanzo (1931) and made no attempt to identify to species. Baird 
(1971) gave an account of the adults. 
Polyipnus spp. (3 occurrences, 6 larvae).—Larvae of this genus 
were rare in these collections. Houde et al. (footnote 4) reported 
the capture of three specimens in the eastern Gulf of Mexico. 
Identification.—Larvae have not been described in the literature. 
I made no attempt to identify these to species. Baird (1971) gave a 
good account of the adults. 
Sternoptyx spp. (26 occurrences, 31 larvae).—These were the 
most abundant sternoptychine larvae, being most abundant dur- 
ing the summer. They are widespread throughout the area. 
Houde et al. (footnote 4) reported capturing 75 specimens in the 
eastern Gulf of Mexico; Ahlstrom (1972) reported that this genus 
accounted for 85% of the sternoptychine species from the eastern 
tropical Pacific. 
Identification.—Larvae have not been described in the literature. 
I made no attempt to identify to species. Baird (1971) gave an ac- 
count of adults. 
7. Stomiatidae 
(3 occurrences, 3 larvae) 
Larvae of this family were rare in these collections. In the 
eastern Gulf of Mexico, eastern tropical Pacific, and western In- 
dian Ocean few larvae of this family were taken (Houde et al. 
footnote 4; Ahlstrom 1971, 1972; Nellen 1973). 
Identification.—\ followed Sanzo (1931) and made no attempt to 
identify the specimens to a lower taxonomic level. 
8. Chauliodontidae 
(14 occurrences, 20 larvae) 
All larvae of this family are in the genus Chauliodus. Four 
times more larvae were taken on the winter cruise; but with so few 
taken, I do not wish to speculate whether this is a true seasonal 
difference or possibly due to specific differences. Houde et al. 
(footnote 4) could not find any seasonality in specimens collected 
in the eastern Gulf of Mexico. Chauliodontid larvae were taken 
most abundantly in a quadrant south of the Equator and closer to 
the continents in the eastern tropical Pacific (Ahlstrom 1971, 
1972).
